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

76/80

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

Answer 2

`(actual - estimated)/(actual)`
=
`(76 - 80)/(76)`
=
`(-4)/(76)`
= -0.0526
= -5.26%
≈ -5.3%
