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

Answer 1

The formula for percent error is:
percent error = |(actual value - estimated value) / actual value| * 100

Given that Keisha estimated Sam's weight as 60 pounds and his actual weight is 75 pounds, we can substitute these values into the formula:

percent error = |(75 - 60) / 75| * 100

Simplifying inside the absolute value:

percent error = |15 / 75| * 100

Taking the absolute value of 15/75:

percent error = (15 / 75) * 100

Simplifying the fraction:

percent error = 0.2 * 100

Calculating the product:

percent error = 20

Therefore, the percent error is 20%.
