To find the percent error, you can use the formula:

\[ \text{Percent Error} = \left( \frac{\text{Actual Value} - \text{Estimated Value}}{\text{Actual Value}} \right) \times 100 \]

In this case, the estimated weight (Krisha's belief) is 60 pounds, and the actual weight is 75 pounds.

First, calculate the absolute error:

\[ \text{Absolute Error} = \text{Actual Value} - \text{Estimated Value} = 75 - 60 = 15 \text{ pounds} \]

Now, substitute the values into the percent error formula:

\[ \text{Percent Error} = \left( \frac{15}{75} \right) \times 100 \]

Calculating this gives:

\[ \text{Percent Error} = \left( 0.2 \right) \times 100 = 20% \]

Therefore, the percent error is 20%.
