To calculate the percent error, you can use the formula:
Percent Error = (|Observed Value - Expected Value| / Expected Value) * 100%
In this case, the observed value is $21,800 and the expected value is $25,500.
Percent Error = (|21800 - 25500| / 25500) * 100%
= (3700 / 25500) * 100%
= 0.144 * 100%
= 14.4%
Therefore, the percent error is 14.4%.
To calculate the percent error, we can use the following formula:
Percent error = ((exact value − approximate value) / exact value) × 100%
In this case, the exact value is $25,500, and the approximate value is $21,800. Let's plug these values into the formula:
Percent error = (($25,500 − $21,800) / $25,500) × 100%
Calculating this expression:
Percent error = ($3,700 / $25,500) × 100%
Dividing $3,700 by $25,500:
Percent error = 0.1451 × 100%
Multiplying 0.1451 by 100:
Percent error = 14.51%
Therefore, the percent error is 14.51%.
The closest answer choice is 14.5%, which is equivalent to our calculated percent error.
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. Finally, we multiply the result by 100 to get the percentage.
The expected cost was $25,500, and the negotiated price was $21,800. So, the difference is $25,500 - $21,800 = $3,700.
To find the percent error, we divide the difference ($3,700) by the expected cost ($25,500) and multiply by 100:
Percent Error = (Difference / Expected Cost) * 100
Percent Error = ($3,700 / $25,500) * 100
Evaluating this expression:
Percent Error = 0.145 * 100
Percent Error = 14.5%
Therefore, the percent error is 14.5%.
