Answer 2

Answer:  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%
