To find the percent error, start by listing the key information from the problem.

The pet store told Kenny the guinea pig would weigh 2 pounds when fully grown.

It actually weighs 1.8 pounds fully grown.

First, find the amount of error. It is the difference between 2 and 1.8, which is 0.2.

Now, use the formula to find the percent error.
