Original price: $?

Discount:20%

Sale price: $14.40

Answer

The original price is $18

Step-by-step explanation:

First, turn the percent into a fraction by dividing by 100.

20% to 0.2

Remember that the original price (x) multiplied by 1 - the discount (0.2) equals the sale price (14.4)

(1-0.2) x=14.4

0.8x=14.4

Divide both sides by 0.8 to get:

x=18
