4. You have developed an innovative new project that is estimated to produce an annual revenue stream (money in) of $15,000 per year for the next 10 years. Your current corporate cost of Money is 4%. However, in year 5, your CFO projects that rate will rise to 6% for the remaining five years of the project's lifespan. What is the NPV of this money in cashflow today? (we are ignoring any money out costs)

Give typing answer with explanation and conclusion A small company purchased now for $120,000 will lose $300 each year for the first four years. An additional $600 in the company in the fourth year will result in a profit of $9500 each year from the fifth through the twelfth year. At the end of 12 years, the company can be sold for $135,000. a) Draw the cash flow diagram b) Determine the IRR for this project. c) Calculate the FW if MARR is 5%. d) Calculate the ERR when ε = 7%.

1. Consider a wine dealer who has k bottles of wine. The dealer can sell them now (t = 0) or can store it for some time and then sell them later. The value of k bottles at t-th month is given by: Vt = ket The dealer can use the sales revenue as principal in a risk-free investment at rate r. (b) Write out the present value PV, of k bottles at t-th month.

Assume r=0.1. What is the present value of the following stream of cash flow? Year 0 Year 1 Year 2 Year Year 4 Year ... 1000 1000 1000 1000 1000 1000 11000 100000 12000 10000

8. (10%) Two pumps are being considered for service in Africa. Each can draw water from a depth of 50 meters and both pumps deliver 60 horsepower (output) to the pumping operation. One of the pumps must be selected. It is expected that the pump will be in use 800 hours per year and electricity costs $0.14 per kilowatt-hour. The following data are available. Recall that 1 hp = 0.746 kW. Capital investment Electrical efficiency Annual maintenance cost Useful life Pump A $2,400 0.92 $320 3 years Pump B $2,000 0.80 $200 6 years The MARR is 15% per year. Determine which alternative should be selected if the repeatability assumption applies.
