Tess planned to buy a truck. She expected to pay $24,500. She negotiated the price so that the final cost was $21,800. Calculate the percent error

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

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

In this case:

  • Expected Value = \(24,500\)
  • Actual Value = \(21,800\)

Now, substitute the values into the formula:

\[ \text{Percent Error} = \frac{21,800 - 24,500}{24,500} \times 100 \] \[ \text{Percent Error} = \frac{-2,700}{24,500} \times 100 \] \[ \text{Percent Error} \approx -11.02 \]

Since percent error is typically expressed as a positive number, we can take the absolute value:

\[ \text{Percent Error} \approx 11.02% \]

Thus, the percent error is approximately \(11.02%\).

Sorry should have been $25,500
