Question

A sofa is on sale for 60% off. The sale price is $184.
What is the regular price?

Answer 1

$460

Explanation:

• Let the regular price of the sofa be $P

• We are given that the sales discount is 60%

• Convert 60% to decimal => 60/100 = 0.6

• So discount in $ terms = P x 0.60 = 0.6P

• Sale price = Regular price - Discount = P(1 - 0.6P) = P(0.4) = 0.4P
  
• We are given that the sale price is $184
  Therefore, 0.4P = 184
  P = 184/0.4 = $460
  

Therefore the regular price of the sofa is $460
