Answer:
Step-by-step explanation:
I think this is the equation for annual compunt interest
FV = PV(1 + int)^time     PV is present value   FV is the future value
PV + Interest  =  FV
FV - PV = Interest
              FV          -    PV
Interest  = [3000(1 + 0.03)^30]  -  3000
       =   3000(1.03)^30   -  3000
       =   3000(2.4272)  -  3000
       =   7281.79  -  3000
       =   $4282   to the nearest dollar   <------------   Fianl Answer
