A store is having a sale where school supplies are 30% off their oiriginal price. A backpack is on sale for $11.20. What was the original price of the backpack

16 dollars.

Step-by-step explanation:

Given that selling price of a back pack after reduced by 30% is 11.20 dollars.

We have to find the original price of the back pack.

Let original price = 100

Reduced % = 30

Selling price = 70

70 dollars is equivalent to selling price of 11.20 $

100 dollars is equivalent to selling price of 100 (11.2) / 70 = 16 $

i. e. original price of back pack is 16 dollars.
