Answer 1

The percent error is calculated by the formula Absolute Value of (Error - Actual / Actual then times 100).

In this case the Error value was 76, and the Actual was 80.

So, set up the expression

I(76 - 80)/80 x 100I

I-4/80 x 100I

I-400/80I

I-5I

The percent error was 5 percent, since that was how much her estimation differed from the actual amount.

5 percent
