Finance: suppose $4000.00 is invested at 4% compounded quarterly. How much money will be in the account A). 3/4 year? B). 15 years?

Answer provided by our tutors

P = $4,000.00 the principal


r = 0.04 or 4% annual rate


m = 4 compounding period per year (compounded quarterly)


i = 0.04/4 = 0.01 interest rate per period


t = number of years


n = t*m = 4t total number of compounding periods


A = the future value


A = P(1 + i)^n


A). 3/4 year?


t = 3/4 years


n = 4*(3/4) = 3


A = 4000(1 + 0.01)^3


A = $4,121.20
