Given:
Selling price of each CD = $5.00
Cost price of each CD = $1.25
Number of CDs ordered = 300
Profit must be at least $500.
To find:
The number of CDs needs to sell.
Solution:
Let n be the number of CDs needs to sell.
Selling price of each CD = $5.00
Selling price of x CDs = $5n
Cost price of each CD = $1.25
Cost price of 300 CDs = 300×$1.25
= $375
We know that,
[tex]Profit=S.P.-C.P.[/tex]
[tex]Profit=5n-375[/tex]
Profit must be at least $500. it means profit must be greater than or equal to $500.
[tex]5n-375\geq 500[/tex]
[tex]5n\geq 500+375[/tex]
[tex]n\geq \dfrac{875}{5}[/tex]
[tex]n\geq 175[/tex]
All options are incorrect. The required inequality is n is greater than or equal to 175.

Mr. Charles gave both of his sons, Joe and Bill, $5,000. Joe deposited the money in an account that offered simple interest of 11% per year. Bill deposited the money in a bank that offered an interest of 9% compounded annually. Who would be richer at the end of 6 years and by what amount? Joe: $ , Bill: $ , . earns more.
Answer:
Bill by $85
Step-by-step explanation:
Bill : Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial amount of the money given is then subtracted from the resulting value.
Compounded annually for 6 years at 9 % interest Bill would have $8385.50.
Joe : Simple interest at 11% a year The formula we'll use for this is the simple interest formula.
P is the principal amount, $5000.00.
r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.
t is the time involved, 6year(s) time periods.
So, t is 6year time periods.
To find the simple interest, we multiply 5000 × 11 × 6 = 3300
Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),
or 5000.00 + 3300.00 = 8300.00
As you can see Bill has more by $85.

Assume, Austin used 2 fractions (a and b)
Such that:

Also:
Assume that:
[tex]a = \frac{2}{3}[/tex]
Note that this could be any fraction, but I chose to use 2/
Make b the subject in [tex]a + b = 3\frac{1}{3}[/tex]
[tex]b = 3\frac{1}{3} - a[/tex]
[tex]b = 3\frac{1}{3} - \frac{2}{3}[/tex]
[tex]b = \frac{10}{3} - \frac{2}{3}[/tex]
Take LCM
[tex]b = \frac{10-2}{3}[/tex]
[tex]b = \frac{8}{3}[/tex]
[tex]b = 2\frac{2}{3}[/tex]
So, the fractions are:
[tex]a = \frac{2}{3}[/tex] and [tex]b = 2\frac{2}{3}[/tex]

Tito used 1 1/8 gallons of paint to paint 3/7 of a fence. How many gallons of paint would it take to paint the whole fence?
1 1/8:3/7
How many gallons does it take to cover 1/7 of the fence?
1 1/8 divided by 3= 9/8 divided by 3/1 or 9/8*1/3=9/24 or 3/8.
It takes 3/8 of a gallon to paint 1/7 of a fence.
7*3/8= 7/1*3/8= 21/8.
I believe your answer is: it takes 21/8 or 2 5/8 gallons of paint to paint the whole fence.

1/2 a = 11 what is a
Answer:
a = 22
Step-by-step explanation:
To find a, divide each side by 1/2, or multiply by the reciprocal:
1/2a = 11
a = 22
So, a = 22
Answer:
a = 22
because when isolate a you move 1/2 over with 11, and when you do that insted of multyplying 1/2 times a you divide 1/2 by 11
Guys I need help. How do I solve 3/4 + 5/8 + 2/3 - 1/6 ?
Answer:
15/8
Step-by-step explanation:
Literally find the common denomiator. That's the first step for any of these computational fraction problems.
Here are the following denomiators: 4,8,3,6. You notice that 24 is a multiple of all the numbers. Thus, our common denomiator is 24. Next we change each fraction based on our new denomiator
3/4 = 18/24
5/8 = 15/24
2/3 = 16/24
1/6 = 4/24
Now we do basic computation
18/24 + 15/24 + 16/24 - 4/24 = 45/24 = 15/8

Which of the following could NOT be true?
A: The missing number is 11
B: The missing number is 20
C: The missing number is 25
D: The missing number is 30
Answer:Median = Mid value of Set of observation
If number of observation is odd, suppose n
Median = th term
If number of observation is even , then
Median = Mean of two middle observation i.e
Data set : 17, 20, 30, 28, 18
Data arranged in ascending order: 17,18,20,28,30
Let one data =x
Number of observation is even.
Given, Median = 24
As , when number of observation is even , median is mean of two mid values.
Median=→→→ getting the median.
So, x must be greater than 30.
The correct option satisfying the above condition is Option (D) 34.
Step-by-step explanation:
Answer:
A. The missing number is 11
Step-by-step explanation:
The highest number in the set is 30 and the lowest is 12, this makes the range 18.
30 is supposted to be there to make the range what the problem says it is: 12.
20 and 25 could be there because no matter what, as long as 30 is the greatest number, 20 and 25 don't effect the range AT ALL.
If 11 was in the number sequence, the lowest number would be 11, making the range 19, (30-11=19) which is not what the teacher is saying the range is.
So in short, A. The missing number is 11 is the correct answer.

There are 15 circles and 9 triangles. What is the simplest ratio of
triangles to circles?
Answer:
9:15
Step-by-step explanation:
The required ratio of the number of triangles to the number of circles is 3:5.
Given that,
There are 15 circles and 9 triangles. What is the simplest ratio of triangles to circles is to be determined.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
Here,
Number of circles = 15
Number of triangles = 9
The ratio of the triangle to the circle,
= Number of triangles / Number of circles
= 9 /15
= 3 / 5
Thus, the required ratio of the number of triangles to the number of circles is 3:5.

Please help find the measurement of exterior angle MBI
Answer:
The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with
N sides. It is equal to 360 o N .
Step-by-step explanation:
Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.
However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to 360 o .
It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of
360 o . So, if all exterior angles are equal, like in a regular polygon, each one equals to 360 o N .
It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is ( N − 2 ) ⋅ 180 o .
Dividing the above by N
we will obtain a value of an interior angle: ( N − 2 ) ⋅ 180o N .
Therefore, exterior angle of a regular polygon is 180 o − ( N − 2 ) ⋅ 180 o N = 360 o N

whats 40 = 1.6m ? help please
Answer:
2.5
Step-by-step explanation:
Divide each side by 1.6 to get m alone, thus getting the answer, so 1.6m/1.6 and 40/1.6
The solution of the equation 40 = 1.6 m is m is equals to 25.
Given Equation:
40 = 1.6m
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
First, write the decimal 1.6 in fraction as 16/10.
So, the equation can be written as
40 = 16/10 (m)
40 x 10 = 16m
400 = 16 m
Now, divide both side of equation by 16
400/ 16= 16 m/ 16
25 = m
Therefore, the value of m is 25.
