A store has 20% off sale on pants. With this discount, the price of one pair of pants before tax is $15.20. What was the original price of the pants?

$19 is the original price

Step-by-step explanation:

Step 1:  Make an equation

A store has 20% off sale on pants. With this discount, the price of one pair of pants before tax is $15.20.

n is the total price, 0.2n is the discount:  n - 0.2n

n - 0.2n = 15.20

Step 2:  Combine like terms

n - 0.2n = 15.20

0.8n = 15.20

Step 3:  Divide both sides by 0.8

0.8n / 0.8 = 15.20 / 0.8

n = 19

 $19 is the original price
