Question

Item 18 You estimate that a puppy weighs 12 pounds. The actual weight of the puppy is 14 pounds. Find the percent error. Round your answer to the nearest hundredth of a percent.

Answer 1

Hi!

First find how much you were off by. 

14-12=2

Now set up a proportion and cross multiply to solve. 

$\frac{2}{14} \frac{x}{100}$

2 x 100 = 200
200/14 = 14.29

The answer is 14.29%
