To calculate the percent error, you can use the following formula:
\[ \text{Percent Error} = \left( \frac{|\text{Estimated Value} - \text{Actual Value}|}{\text{Actual Value}} \right) \times 100 \]
Given:
- Estimated Value = 56
- Actual Value = 43
Now, plug in the values:
\[ \text{Percent Error} = \left( \frac{|56 - 43|}{43} \right) \times 100 \]
First, calculate the absolute difference:
\[ |56 - 43| = 13 \]
Now substitute this into the formula:
\[ \text{Percent Error} = \left( \frac{13}{43} \right) \times 100 \]
Now calculate \( \frac{13}{43} \):
\[ \frac{13}{43} \approx 0.3023 \]
Multiply by 100 to convert to a percentage:
\[ 0.3023 \times 100 \approx 30.23% \]
So the percent error is approximately 30.2%.
The correct answer is 30.2%.
