Question

Jimmy thought he had purchased 7folders, but he had only purchased 6.What was his percent error? round to the nearest percent

Answer 1

We can define the percent error as the difference between the estimated value and the actual value, divided by the actual value.

In this case, the estimated value (what Jimmy thought he had purchased) is 7 and the actual value is 6.

Then, the percent error is:

`e=(E-A)/(A)=(7-6)/(6)=(1)/(6)\cdot100\%=16.666\ldots\%\approx16\%`

The percent error is 16%.
