6. Frank wants to save $3200 to take a vacation in 3 years. To the nearest dollar, how much will he need to invest in an account now with 4.5% APR compounding monthly?
Solution
amount = $ 3200
time = 3 years
rate of interest = 4.5% compounded monthly
applying compounded monthly formula
A = P ( 1 + r/n)^nt
3200 = P ( 1 + .045 / 12 )^12*3
3200 = P ( 1 + .045 / 12 )^36
P = 2796.6
so he must invest $ 2797 now
