Mighty Max started the wrestling season weighing 135 pounds. By the time the season ended, he weighed 128 pounds. What was the percent decrease in his weight? That is, what was his decrease in weight as a percent of his starting weight?

5%

Explanation:

We will apply weight loss formula here:

Divide weight loss by starting weight. Then, multiply the resulting value by 100. You will get decrease in weight as a percent.

About this question:

135 pounds = starting weight

135 pounds - 128 pounds = 7 pounds (i.e. weight loss)

Now, according to formula:

7 ÷ 135 = 0.05

0.05 × 100 = 5%
