CMGT 357/457 Fall 2015 Homework#1 – Paper Portion Due: Sep. 9, 2015 (3 points each = 18 points total) 1. You are deciding between three types of water heaters. The associated costs are shown below. The annual cost of operation for gas and oil heaters is estimated by 365 x 41045/EF x Fuel Cost per Btu, and the annual cost of operation for electric water heaters is estimated by 365 x 12.03/EF x Electricity Cost per kWh. The selected heater will be used for only one year and then sold at the market value. Which alternative should be selected? Alternative Electric Gas Oil Price of water heater \$28,000 \$23,000 \$25,000 EF 2.0 0.57 0.75 Fuel cost \$0.1/kWh \$0.00001/Btu \$0.00001/Btu Annual maintenance costs \$3000 \$2200 \$2500 Market value \$25,200 \$20,700 \$22,500 2. Your friend borrows \$1,000 from you and agrees to pay it back in 6 months. Because they are your friend, you are only charging them simple interest at the rate of 1% per month. How much will your friend owe after 6 months? How much is the interest alone? 3. Compare the amount of interest earned by an initial investment of \$5,000 after 30 years if the interest is (a) 6% simple interest per year, and (b) 6% interest compounding annually. 4. A friend has a 5-year loan of \$20,000, with a monthly interest rate of 1%. Her monthly payments are \$445. Draw the cash flow diagram for this situation. 5. If Michael invests \$9,500 at 8% compounded continuously, how much would it be worth in four years? 6. This week you decide to start contributing \$10 per week (\$520 total per year) into an account that earns 8% interest (compounded annually). How much money would you have saved by the end of 40 years?
