-It is now January 1. You plan to make 5 deposits of $300 each, one every6 months, with the first payment being made exactly six months from today. If the bank pays a nominal interest rate of 12% but uses semiannual compounding, how much will be in your account exactly 12yearsfrom today?

-You must make a payment of $3,800 exactly 8 years from today. To prepare for this payment, you will make 5 equal deposits into an account that pays a nominal interest rate of 7.6% p.a., with quarterly compounding. If your first deposit is made today (and then you make four additional deposits in each of the next four quarters that is, a deposit 3 months from today, another 6 months from today and so on), what must each of the 5 payments be for you to exactly achieve your goal?
