Find the percent of change the original cost was 50. And the new cost is 60

20%

Step-by-step explanation:

First get the increase of the cost.

Increase = 60 - 50 = 10

The percentage change is the increase divided by the original cost multiplied by 100%

That's

10/50 x 100%

0.2 x 100%

20%

The percentage change is 20%
