Question

A store increases the price of a sweater from $20 to $22.

What is the percent of increase?

Answers choices are 0.1, 0.2 , 2 , 9, 10 , 20

Answer 1

The sweater was increased in price by 10 percent.

Answer 2

percent increase : (new number - original number) / (original number)...x 100

(22 - 20) / 20 = 2/20 = 0.1.....0.1 x 100 = 10...so there is a 10% increase
