Question

Tyler bought shoes for $72. The next week he noticed that the price went

up to $87. What was the percent increase (percent change)? Round your
answer to the nearest whole percent. *

Answer 1

Percent increase is 21%

Explanation:

Initial cost of shoes = $72

New price of shoes = $87

Increase in price of shoes = New price of shoes - Initial cost of shoes

=
`87-72`

= $15

Percentage increase in price of shoes = ( Increase in price of shoes ÷ Initial cost of shoes) × 100

=
`(15)/(72)(100)=20.8\%`

≈ 21%

So, percent increase is 21%
