Answer:
$202.50
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
