Prоblem 1 (15 pоints) A sum оf $150,000 now аt аn interest rаte of 10% per year compounded semiannually. What is the effective interest rate if the CP is semiannually? What is the effective interest rate if the CP is annually? The $150,000 is equivalent to how much money 6 years ago? How much is the interest in the $150,000? Problem 2 (15 points) The annual worth for years 1 through 8 of the cash flows shown is $2,500. What is the amount of the cash flow labeled X in year 3, if the interest rate is 10%? Problem 3 (20 points) Three alternatives to incorporate improved techniques to manufacture a computer drives have been developed and costed. Compare the alternatives below using capitalized cost and an interest rate of 24% per year compounded quarterly. Problem 4 (20 points) The cash flow of Machines E and F is shown in the table below. Give the incremental cash flow between machines E and F at year 0: at year 5: at year 8: at year 10: Draw the incremental cash flow diagram Determine the maximum number of Δi* that may satisfy the ROR relation. Write down the PW relation for calculating Δi* (equation only, no calculation needed) Write down the AW relation for calculating Δi* (equation only, no calculation needed) Problem 5 (15 points) The four alternatives described in the tables below are being evaluated. If the proposals are independent, which one(s) should be selected at a MARR of 17% per year? Justify your answer. If the proposals are independent and the budget is $100,000, which one(s) should be selected at a MARR of 15% per year? Justify your answer. If the proposals are mutually exclusive, which one should be selected at a MARR of 14.5% per year? (show the evaluation procedure) Problem 6 (15 points) Four Different machines are under consideration for improving material flow in a certain production process. An engineer performed an economic analysis to select the best machine, but some of his calculations were erased from the report by a disgruntled employee. All machines are assumed to have a 10-year life. Give the missing numbers in the report. (total 5, write down the calculation for each) If the MARR is 8% per year and one of the machines must be selected, which machine should be selected? (show the evaluation procedure) Bonus problem (10 Points) Jeremy bought a new house. He decided to finance $300,000 from a bank. The bank provides a 30-year loan with zero down-payment and annual installments (6% APR). Demonstrate that the interest paid in the first five years is (1) more than 1/5 of the total interest of this loan and (2) more than 80% of the total payment in five years.
