Answer:
Step-by-step explanation:
Part A:
Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then
50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400
Therefore, the retail price of the mattress, before the discount is $2,400.
Part B:
Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then
(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.
Therefore, the wholesale price, before the markup was $960
82 / n - 26 is the correct expression (that's the 4th choice).
Choice 2 is also correct. Also the 5th is correct.
82 / 2 - 26
= 41 - 26 = 15
So the last choice is also correct.

Answer:
y = 7
Step-by-step explanation:
Subtract 9 from both sides.
-7 = -y
Divide both sides by negative 1 (or multiply by negative 1).
7 = y
So, in mathematical terms, y = 7.
Hope this helps! :)
The area is 144 units.
area is length × width
squares have an equal lenght and width, and 4 sides. if a square's perimeter is 48, we need to divide that by 4 to get the size of each side.
48 ÷ 4 = 12
each side is 12 units. to get the area, we need to mutliple length × width, in this case 12 × 12, which equals 144 units.
