Question

Oliver estimates the weight of of his cat to be 16 pounds. The actual weight of the cat is 14.25 pounds. What is the percent error of Oliver's estimate rounded to the nearest tenth of a percent.

Answer 1

Given:

Estimated weight of a cat = 16 pounds

Actual weight of that cat = 14.25 pounds

To find:

The percent error to the nearest tenth of a percent.

Solution:

We know that,

$\text{Percent error}=\dfrac{\text{Estimated value - Actual value}}{\text{Actual value}}\times 100$

Using the above formula, we get

$\text{Percent error}=\dfrac{16-14.25}{14.25}\times 100$

$\text{Percent error}=\dfrac{1.75}{14.25}\times 100$

$\text{Percent error}=0.122807\times 100$

$\text{Percent error}=12.2807$

Round the percent error to the nearest tenth of a percent.

$\text{Percent error}\approx 12.3$

Therefore, the percent error is 12.3%.
