Question

31. Original price: ?Discount: 20%Sale price: $75What is original price

Answer 1

Given:

We will find the original price, let it = x

Discount: 20%

Sale price: $75

As the discount = 20%

So, the sale price = 100 - 20 = 80%

So, 80% of x = 75

Note 80% = 80/100 = 0.8

So, we can write the following equation:

`\begin{gathered} 0.8x=75 \\ x=(75)/(0.8)=93.75 \end{gathered}`

So, the answer will be the original price = $93.75
