Question

Mindy's dog, Rex, weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight?

A) 15%

B) 16%

C) 13%

D) 12%

Answer 1

A) 15%

Explanation:

To find the percent increase, use the equation:

`\text{percent of increase}=\frac{\text{amount of increase}}{\text{original amount}}`

The amount of increase is 92-80 = 12. The original amount of 80; this gives us

12/80 = 0.15 = 15%

Answer 2

A) 15% because 80+15%=92
