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

To find the percent error, we use the formula:

Percent error = (|Actual value - Estimated value| / Actual value) * 100

In this case, the actual weight of Sam is 75 pounds, and Krisha estimated the weight to be 60 pounds.

Plugging in these values, we get:

Percent error = (|75 - 60| / 75) * 100
Percent error = (15 / 75) * 100
Percent error = 0.2 * 100
Percent error = 20%

Therefore, the percent error is 20%.
