Find the percent of change.

The original cost was $50 and the new cost is $60.

Increase of 20%

Increase of 10%

Increase of 16.67%

Decrease of 10%

Increase of 20%

Step-by-step explanation:

percent change = (new value - old value) / (old value) * 100%

Here, the new value is $60, and the old value is $50.

percent change = ($60 - $50) / ($50) * 100%

percent change = ($10) / ($50) * 100%

percent change = 1/5 * 100% = 0.2 * 100%

percent change = 20%

Since the percent change is positive, it is a percent increase.

Answer: Increase of 20%
