A=P(1+r/n)^nt
this is where
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
A=220*(1+0.09/4)^(4*5)
A= 220*1.0225^20
A= 220*1.56
A= 343.2
$343.2 is the answer
