Erik bought a mattress that was marked down 70% from an original price of $500. If the sales tax in Oak Grove is 8%, what was the total cost of the mattress?
Answer:
Btw the result are this: 70% = 0.7500 = 0.78% = 0.08 In Oak Grove
Step-by-step explanation:
The total cost of the mattress is $162 after markdown 70% and sales tax 8%
Given :
Erik bought a mattress that was marked down 70% from an original price of $500
Original price is 500 dollars
marked down that is discount percentage is 70%
Lets find the discount amount using original price
markdown percentage times original price
[tex]discount = \frac{70}{100} \cdot 500=350[/tex]
cost of mattress after discount is 500-350= 150 dollars
sales tax is 8%
now we find the tax amount for 150 dollars
[tex]tax=150 \cdot \frac{8}{100} \\tax = 12[/tex]
tax is 12 dollars
the total cost of the mattress= cost of mattress +tax
the total cost of the mattress=150+12=162
the total cost of the mattress is $162

2. When a number n is subtracted from 18
and the difference is divided by n, the
result is 2. What is the value of n?
(A) 4
(B) 6
(C) 8
(D) 10
(E) 14
Answer:
e) 14
Step-by-step explanation:
(18-n)/2 = 2
18-n = 4
-n = -14
n = 14
The value of n when n is subtracted from 18 and the difference is divided by n, the result is 2 is 6.
What is Algebra?The representation of mathematical statements as solutions to problems is the focus of the branch of mathematics known as algebra. Mathematical operations like addition, subtraction, multiplication, and division are combined with variables like x, y, and z to produce a meaningful mathematical statement.
Given:
When a number n is subtracted from 18
=(18- n)
and, the difference is divided by n
=(18 - n)/n
so, result is 2
(18 - n)/n = 2
18 - n = 2n
3n = 18
n= 18/3
n= 6
Hence, the value of n is 6.

A line segment is also a line but a line with finite length and fixed endpoints. The length of the line segment FH is 7 units.
What are a line and line segment?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
A line segment is also a line but a line with finite length and fixed endpoints.
Given that the length of the line segment HG is 15 units and the length of line segment FG is 22 units.
Since the line segment, FG is made from FH and HG. Therefore, we can write,
FG = FH + HG
22 units = FH + 15 units
FH = 22 units - 15 units
FH = 7 units
Hence, the length of the line segment FH is 7 units.

Together, Sala and Terry saved $10.00. Sala. saved D dollars. Write an expression for the amount Terry saved.
Let Terry Saved be T dollars .
The Expression will be
[tex]\\ \rm\longmapsto Sala+Terry=\$10.00[/tex]
[tex]\\ \rm\longmapsto D+T=\$10.00[/tex]
Answer:
T = 10 - S
Step-by-step explanation:
The only useful information is that they saved $10 together. We are just going to add the money Sala and Terry saved to equal 10.
S + T = 10
They want an expression for how much Terry saved so we can solve for T.
T = 10 - S

if (x+30°) and (180°-2x) are vertically opposite angles . Find the value of x .
Answer:
50
Step-by-step explanation:
x + 30 = 180 - 2x [vertically opposite angles]
x = 180 - 30 - 2x
x = 150 - 2x
x + 2x = 150
3x = 150
x = 150/3
x = 50

Answer:
the second option is correct
raise the quotient of y and 5 to the 2nd power
Answer:
I'm guessing y is numerator and 5 is denominator. so y^2/25
Step-by-step explanation:
so if you have the fraction y/5 and you need to square it or raise to the second power you get (y/5)^2. now using the properties of exponents when you get a fraction and need to raise it to a power you square the denominator and numerator which gets you y^2/25. now let's check if it works we can use 5 for y so (5/5)^2 is equal to 25/25 = 1. or (10/5)^2 which is 2^2 = 4. or 100/25 which is 4. so the equation works for the expression.
Petra invests $10,800. After 4 years she has earned $3240 in interest.
At what annual rate of interest did she invest her money?
Answer:
Rate =interest*100/principal*time
Rate = 7.5%
Step-by-step explanation:
At 7.5 % annual rate of interest did she invest her money.
What is rate of interest?The percentage usually on an annual basis that is paid by the borrower to the lender for a loan of money is called rate of interest.
Given
Principal P = $10800
Time t = 4 years
I = 3240
Interest = [tex]\frac{P\times r \times t}{100}[/tex]
[tex]3240 = \frac{10800\times r \times 4}{100}[/tex]
[tex]r= \frac{3240\times 100}{10800\times 4}[/tex]
r = 7.5 %
At 7.5 % annual rate of interest did she invest her money.
