Question

Tom weighed 80 pounds last week, and now he weighs 80 pounds. By what percent has his weight increased?

A. 0%
B. 10%
C. 20%
D. 100%

Answer 1

Tom's weight has not changed; it remained at 80 pounds, which indicates a 0 percent increase in weight.

Step-by-step explanation:

If Tom weighed 80 pounds last week and he still weighs 80 pounds now, then his weight has not increased. To calculate the percentage increase in weight, we would use the formula:

Percentage Increase = ((New Weight - Original Weight) / Original Weight) x 100%

Substituting the values we have:

Percentage Increase = ((80 - 80) / 80) x 100% = (0 / 80) x 100% = 0%

Therefore, by what percent has Tom's weight increased? It would be 0 percent.
