The Ecology Group wishes to purchase a piece of equipment for recycling of various metals. Machine 1 costs $123,000, has a life of 10 years, an annual cost of $5,000, and requires one operator at a cost of $24 per hour. It can process 10 tons per hour. Machine 2 costs $70,000, has a life of 6 years, an annual cost of $2,500, and requires two operators at a cost of $24 per hour each to process 6 tons per hour. Assume interest rate at 7% per year and 2080 hours per work year. Determine the annual breakeven tonnage of scrap metal and select the better machine for a processing level of 1,500 tons per year.
5) The University has just invested $9,000 in a new desktop publishing system. From past experience, annual cash
returns are estimated as
A(t) $8000 - $4000(1 + 0.15)t- 1
S(t) $6000(1 0.3)t
where A(t) stands for the net cash flow in period t and S(t) stands for the salvage value at the end of year t, and t 2
1.
If the MARR is 12%, compute the annual equivalent cost in year 2
If mutually exclusive projects with normal cash flows are being analyzed, the net present value (NPV) and internal rate of return (IRR) methods
always
agree.
Projects Y and Z are mutually exclusive projects. Their cash flows and NPV profiles are shown as follows.
