Y u Yan planned to buy a new truck. She expected to pay$25,500. She negotiated the price so that the final cost was $21,800. Calculate the percent error.

Question

A. 0.1697%
B. -17%
C. 17%
D. 14.5%

Answer 1

To calculate the percent error, we first need to find the difference between the expected cost and the final cost.

Difference = Expected Cost - Final Cost
= $25,500 - $21,800
= $3,700

Then we divide the difference by the expected cost and multiply by 100 to find the percent error.

Percent Error = (Difference / Expected Cost) * 100
= ($3,700 / $25,500) * 100
= 0.1447 * 100
= 14.47%

Therefore, the percent error is approximately 14.47%. The closest answer choice is D. 14.5%.
