1) You are the investment manager for a local government.Exactly 4 years ago you invested some of the governments money in the bond market by purchasing a 20-year semiannual term bond with a face value of $10,000.At the time of purchase, the bond had a coupon rate of 4.5%.The current market rate for similar bonds is 3.9%, so you decide to sell the bond and immediately invest the money in a new investment account that offers a 5.1% interest rate, compounded monthly.How much will the governments investment account be worth 10 years from today?

Assume that you are the nursing administrator for the medical group that expects a severe outbreak of flue this winter. You hire additional staff to treat patients and administer shots. Your special project budget was for 1,000 hours of part-time nurses services at $40 per hour, for a total cost of $40,000. It was expected that these nurses would treat 2,000 patients. After the flu season was over, it turned out that the total spent on part-time nurses was $50,000. The nurses worked 1,200 hours and 2,600 patients were treated. Calculate the variances. Was the overall result favorable or unfavorable?

Fifteen years ago, Meals for the Homeless bought a new building for $600,000. They borrowed $500,000 on a 30-year mortgage with a 6 percent fixed rate and monthly payments. The current outstanding balance on the mortgage is $355,000. Today, they can get a 15-year fixed-rate mortgage with an interest rate of 4.32 percent. The mortgage would require monthly payments in arrears. It will cost Meals $20,000 to do the refinancing. Should Meals refinance the mortgage under those terms?

Hints: Since you know Meals could use the $20,000 it will cost to refinance the mortgage to pay off some of the principal on its current mortgage, you have decided to use interest rate on the existing mortgage as the discount rate for your analysis. Be sure to include the cost of refinancing in the amount you intend to borrow.
