Yu 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. (1 point)
To calculate the percent error, we need to find the difference between the expected cost and the actual cost, and then divide that difference by the expected cost.
The difference between the expected cost and the actual cost is $25,500 - $21,800 = $3,700.
To find the percent error, we divide the difference by the expected cost and multiply by 100:
Percent error = ($3,700 / $25,500) * 100 ≈ 14.51%
Therefore, the percent error is approximately 14.51%.
