Answer:
14
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 16 only from one side then the equation would change so it's an important rule to bare in mind when solving equations, that you need to keep both sides of the equation the same.
4 ( d + 4 ) = 72
→ Expand the brackets
4d + 16 = 72
→ Minus 16 from both sides to isolate 4d
4d = 56
→ Divide both sides by 4 to isolate d
d = 14

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
