Krisha has a chocolate Labrador retriever named Sam. She believes her dog weighs 60 pounds. Sam’s actual weight is 75 pounds. Find the percent error.

Answer 1

The percent error is calculated by using the formula (|calculated-actual|/actual) * 100.

The calculated weight is 60 pounds.
The actual weight is 75 pounds.

|60-75|=15
15/75=0.2

0.2*100=<<0.2*100=20>>20 percent

So, the percent error is 20%.
