The monthly repayment of $145.59 is less than expected monthly payment of $150, hence, the individual can afford tp purchase the car on finance
How do we determine affordability in this case?
In order to determine whether the individual can afford to purchase the car on finance, we need to ascertain the monthly payment of the loan based on the terms of deal provided which would be compared to the expected monthly repayment of $150 using a financial calculator as below:
N=60(number of monthly payments in years=5*12)
I/Y=15.9/12(monthly interest rate without the % sign)
PV=-6000(loan principal)
FV=0(after 60 monthly payments, the balance would be nil)
CPT(press compute)
PMT=$145.59

an angle measures 85.2 less than the measure of its supplementary angle. what is the measure of each angle? it should be 2 angles or answers. please answer quick. i will mark brainliest. thank you
Answer:
47.4°, 132.6°
Step-by-step explanation:
Given the difference of two angles is 85.2° and their sum is 180°, you want to find their measures.
SetupLet the smaller angle be represented by x. Then the larger angle is (x +85.2). Their sum is ...
x +(x +85.2) = 180
SolutionSimplifying the equation, we get ...
2x +85.2 = 180
2x = 94.8 . . . . . . . . subtract 82.5
x = 47.4 . . . . . . . divide by 2
x +85.2 = 132.6
The two angles are 47.4° and 132.6°.

5. Daunte's favorite video game store is running a clearance sale. Every week until
everything is sold, the store's owner is going to reduce the price of the remaining
merchandise by 25%. Duante figures that he should wait 4 weeks to go to the
store because then the merchandise will be 100% off! Construct a mathematical
argument involving an exponential function to explain whether Daunte is correct
or incorrect.
Daunte is incorrect. After 4 weeks, the price would be 68.5 percent off.
Is Daunte correct?An exponential function is a mathematical function that has the form : f(x) = a^x
Where:
a = constant x = variableAn exponential function indicates that the quantity is either increasing at a faster rate or reducing at a faster rate. This is true because an exponential increase or decrease is faster than a linear increase or decrease. In a linear increase or decrease, the function is either increasing or decreasing at a constant value.
The price of the video games would reduce by 25% of the previous weeks' price. Thus, the function that would represent this is an exponential function.
The form of the exponential equation would be:
Price after 4 weeks = Initial price x (1 - percentage decrease)^number of years
Let's assume that the initial price is 100
100 x (1 - 0.25)^4
100 x (0.75)^4 = 31.64
The total percentage decrease in the price of the good: (current price initial price) - 1

Colin is borrowing money from his parents to purchase a $700
computer. He will pay them $35 per month for two years. Determine the
simple interest rate on Colin's loan.
Colin paid the loan at a ten percent annual interest rate.
Simple interest is the form of interest calculation in which the principal amount remains the same for the entire duration for which the loan is taken.
It is also assumed that Colin will repay $35 per month for the next two years.
We must calculate a simple interest rate on Colin's borrowings.
As a result, Colin's total payment to his parents for two years is $35.
We are required to find simple interest rate on Colin's borrowings
Therefore, total amount paid by Colin to his parents= 35$ for 2 years
=35*24=840
The amount paid by Colin is principal + interest
Thus, the simple interest amount= 840-700=140$
We know that the simple interest formula is principal*rate*time/100.
We know that the simple interest is 140, the principal is 700, the time is two years, and we need to find the rate of interest.
SI= P*R*T/100
140= 700*R*2/100
140/7*2=R
R=140/14=10
Therefore, The Rate of interest on which Colin paid the loan is 10 per cent per annum

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of Strength
25% antifreeze to get a mixture that is 40% antifreeze? Use the six-step method.
The number of gallons that must be needed to antifreeze 50% solution is 105.
Given that 50% antifreeze solution must be mixed with 70 gallons of Strength 25% antifreeze to get a mixture that is 40% antifreeze.
The six-step method involves a few steps that need to perform. These are defining the problem, determining the root cause, finding the alternative solution to solve the problem, selecting the solution, implementing the solution, and finally evaluating the outcome.
Let's consider x be the number of gallons of a 50% antifreeze solution.
As we know we need to make an antifreeze solution by adding the given quantities.
Hence,
x×50%+70×25%=40%×(x+70)
x×0.5+70×0.25=0.4×(x+70)
Now, we will multiply the numbers, we get
0.5x+17.5=0.4(x+70)
Now, we will multiply both sides by 10, we get
0.5x×10+17.5×10=0.4(x+70)×10
5x+175=4(x+70)
5x+175=4x+280
Further, we will subtract 175 from both sides, we get
5x+175-175=4x+280-175
5x=4x+105
Furthermore we will subtract 4x from both sides, we get
5x-4x=4x+105-4x
x=105
Hence, 105 gallons of 50% antifreeze solution must be needed.

A musician kept track of the concert arenas on this year's tour and found that 60% of the arenas were sold out. Of those that were not sold out, 25% had been on the previous tour schedule from last year, while 90% of those that were sold out were on the previous tour schedule. Which of the following represents the joint relative frequency of arenas that were sold out and not on the previous tour schedule?
75%
54%
30%
6%
Answer:
6%
Step-by-step explanation:
First, let's break this down:
60% of arenas sold out
90% had been on previous tourOut of those arenas that did NOT sell out
25% had been on previous tourWe want to know the joint relative frequency of area that were sold out AND NOT on the previous tour schedule, therefore all the information about areas that did NOT sell out is irrelevant.
Because 90% of the areas that were sold out had been on the previous tour, 10% had NOT been on the previous tour.
Therefore, considering all the arenas, 10% of 60% of the arenas were sold out and not on the previous tour.
Let x equal the total number of arenas:
[tex](.10)(.60)x=0.06x[/tex]
Convert to percent
6%
Therefore, the joint relative frequency of sold out arenas that were not on the previous tour is 6%.

A customer paid a total of $6.00 for 68 copies at a print shop. Some of the copies were black-and-white copies, and the rest were color copies.
• Each black-and-white copy cost $0.08.
• Each color copy cost $0.15.
How many copies of b, the number of black-and-white, and c, the number of color did the customer pay for?
The number of black-and-white is 60 and the number of color copies is 8.
How to calculate the value?Let b = the number of black-and-white.
Let c = the number of color copies.
The equation will be:
b + c = 68
0.08b + 0.15c = 6
Multiply equation I by 0.08
Multiply equation ii by 1.
0.08c + 0.08c = 5.44
0.08b + 0.15c = 6
Subtract
0.07c = 0.56
c = 0.56/0.07
c = 8
Since b + c =68
b= 68 - 8 = 60
Therefore, the number of black-and-white is 60 and the number of color copies is 8.

In a discount clothing store, all sweaters are sold at one fixed price and all shirts are sold at another fixed price. If one sweater and four shirts cost $47, while four sweaters and three shirts cost $84, find the price of one sweater and the price of one shirt.
Answer:
Step-by-step explanation:
Let x be the sweater
Let y be the shirt
Equation1: x+4y=47
Equation2: 4x+3y=84
Now solve for x in the first equation:
x+4y=47
x=47-4y
Now that we've solved for x, substitute the value for x which is 47-4y into Equation2 as follows:
4x+3y=84
4(47-4y)+3y= 84
188-16y+3y= 84
188-13y= 84
-13y= 84-188
-13y= -104
y= -104/-13
y= 8
Now plug in the value for y which is 8 into Equation 1 and solve for x:
x+4y=47
x+4(8)=47
x+32=47
x=47-32
x=15
You can perform a check by plugging in the x and y values into equations 1 and 2 which should yield true statements.
The answer is: 1 sweater costs $15 and 1 shirt costs $8

2x-y+2z=-6
-3y+z=-2
2x-3z+4
The solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7
How to solve the system of equations?The system of equations is given as
2x - y + 2z = -6
-3y + z = -2
2x - 3z = -4
Subtract 2x - 3z = -4 from 2x - y + 2z = -6
This is represented as
(2x - y + 2z = -6) - (2x - 3z = -4)
This gives
- y + 5z = -2
Multiply - y + 5z = -2 by 3
-3y + 15z = -6
Subtract -3y + 15z = -6 from -3y + z = -2
This is represented as
(-3y + z = -2) - (-3y + 15z = -6)
This gives
-14z = 4
Divide by -14
z = -2/7
Substitute z = -2/7 in - y + 5z = -2
- y - 5 * 2/7 = -2
This gives
- y - 10/7 = -2
Rewrite as:
y = 2 - 10/7
Evaluate
y = 4/7
Substitute z = -2/7 in 2x - 3z = -4
2x - 3 * 4/7 = -4
This gives
2x - 12/7 = -4
So, we have:
2x = 12/7 - 4
Evaluate
2x = -16/7
Divide by 2
x = -8/7
Hence, the solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7
