Answer:
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.
