Answer:

D. 20%

Step-by-step explanation:

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

The new number is the increased price, $42, and the old number is the original price, $35.

percent change = ($42 - $35)/($35) * 100%

percent change = ($7)/($35 min) * 100%

percent change = 0.20 * 100%

percent change = 20%

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

The percent increase was 20%.

Answer: D. 20%
