Marie worked two weeks during her college semester break. She earned $870 the first week and $345 the second week. If half of her total earnings went to taxes and 1/3 went to college tuition, how much money did she have left?

$202.50

Step-by-step explanation:

First and foremost her total earnings is the sum of the first week earnings and second week i.e $870+$345=$1215

Taxes =1/2*total earnings =1/2*1215 =$607.5

college tuition =$1215*1/3=$405

The amount that Marie had left is total earnings minus taxes as well as college tuition

amount left in the hands of Marie=$1,215-$607.5-$405=$202.5

In a nutshell Marie has $202.5 left after she has settled the tax bill on her earnings plus the college tuition
