If an item that originally cost $14 is increased to $22, what is the percentage of increase in the item?

= 57.14%

Step-by-step explanation:

Percent increase = (new - original) / original * 100 %

We know the new = 22

and the original = 14

Percent increase = (22 - 14) / 14 * 100 %

= 8/14 * 100%

=.571428571 * 100 %

= 57.14%
