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% because 80+15%=92

Answer 2

Answer:

A) 15%  

Step-by-step 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%
