1 answer

To calculate the percent error, you can use the following formula:

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

In this case:

  • Expected Value = $25,500
  • Actual Value = $21,800

Now, plug these values into the formula:

\[ \text{Percent Error} = \left( \frac{25,500 - 21,800}{25,500} \right) \times 100 \]

Now, calculate the difference:

\[ 25,500 - 21,800 = 3,700 \]

Now, substitute back into the formula:

\[ \text{Percent Error} = \left( \frac{3,700}{25,500} \right) \times 100 \]

Now calculate:

\[ \frac{3,700}{25,500} \approx 0.1455 \]

Then multiply by 100 to convert to a percentage:

\[ 0.1455 \times 100 \approx 14.55% \]

So, the percent error is approximately 14.5%. Therefore, the correct answer is:

b) 14.5%.
