Question

oliver saves ​10% of his weekly earnings for living expenses. he usually makes ​$520 each week. This week made 10​% more. oliver incorrectly claims that he has ​$520 left for spending money oliver this week. Calculate the amount of spending money has left for this week. What error did likely​ make?

Answer 1

Explanation:

10% of $520 is $52, so that's what Oliver usually saves each week.

This week he earned 10% more, which is $52. $520 + $52 = $572

10% of $572 is $57.20

His pay minus his living expenses is $572 - 57.20

He has $514.80 to spend

Since 10% of $520 is $52 and that's what he usually saves, it looks like he just went with that instead of adding the $52 to the $520 and then deducting 10%
