    a=p(1+r)^t
    a=final number
    p=principal balance (initial)**without interest**
    r=interest rate
    t=the amount of time
    p=$4000
    t= 7yrs
    r=2%=0.02
    we need to turn 2% into a decimal, to do that you divide 2 by 100 which is 0.02
    now we rewrite the equation-
    a=4000(1+0.02)^7
    a=4000*1.1486
