Margie calculated that she would spend $175 on school she actually spent $97.50 on school supplies what is Margie percent of error

Answer 1

To calculate the percent error, you would use the formula:

Percent Error = [(|Actual Value - Estimated Value|) / |Actual Value|] x 100%

In this case, Margie's actual spending was $97.50, and her estimated spending was $175. Plugging in the values, we get:

Percent Error = [(|97.50 - 175|) / 175] x 100%
Percent Error = [||77.5| / 175] x 100%
Percent Error = [77.5 / 175] x 100%
Percent Error = 0.442857 x 100%
Percent Error ≈ 44.29%

Therefore, Margie's percent of error is approximately 44.29%.
