Answer:
Interest will amount to $142.58
Total amount Levi will have to pay back at the end of 6 months=$7271.58
Step-by-step explanation:
Simple interest=principal×rate×time
Principal=$7129
Rate=4%=0.04
Time=6 month=0.5 year
=$7129×0.04×0.5
=$142.58
Total amount Levi will have to pay back at the end of 6 months
=principal + total interest
=$7129+$142.58
=$7271.58
