Explanation / Answer
1. A retirement account has $40,000 in it and earns 12% interest per year compounded monthly. At the end of every month for the next 12 years you will deposit $200 into this account. How much will be in the account at the end of 10 years? (Round to the nearest dollar.)
pv =40000, rate =12/12 =1% , nper = 10*12 = 120, pmt = 200
Amount at the end of 10 year = fv(rate,nper,pmt,pv)
Amount at the end of 10 year = fv(1%,120,200,40000)
Amount at the end of 10 year = $ 178,023
