Question

Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.

Answer 1

The percent error compares the absolute error

Explanation:

Answer 2

Absolute error is defined as the magnitude of the difference between the exact value and the approximation.

Here both the times, the error is 15.

40-25=15 and 75-60=15

No, the percent error is not same because the exact values are different and hence, the percent error is different.

Percent error value in 1st case is :

`40-25=15`

error percent is=
`(15)/(40)*100=37.5`%

Percent error value in 2nd case:

`75-60=15`

error percent is=
`(15)/(75)*100=20`%
