Question

You estimate that there are 80 marbles in a jar. the actual amount is 76 marbles. find the percent error. round to the nearest tenth of a percent if necessary.

Answer 1

$\frac{actual - estimated}{actual}$
= $\frac{76 - 80}{76}$
= $\frac{-4}{76}$
= -0.0526
= -5.26%
≈ -5.3%

Answer 2

76/80

Just divide 76 out of 80 and round it to the nearest hundredth Or at least that’s what I think
