Equipment replacement. Copy Center is considering replacing one of its copiers. The new copier will cost $$90,000$; it has an expected life of three years with zero salvage value. The company expects that the new copier will generate $$40,000,$ $$35,000,$ and $$25,000$ in after$-$tax cash flows, respectively, in the first, second, and the third year of operations. The firm$$s manager, however, informs you that this estimate does not include the depreciation tax shield. The old copier has a book value of $$5,000$ but can be sold for $$12,000.$ The old copier will last three more years with careful maintenance. Demand, though, is expected to be lower because the old copier lacks the features of the new copier. The company projects that the old copier will generate $$10,000,$ $$8,000,$ and $$5,000,$ respectively, in after$-$tax cash flows over the next three years. Again, this estimate excludes any tax shield arising from depreciating the old copier. At the end of three years, this old copier will have no salvage value. Copy Center uses a cost of capital of $12\%$ for discounting purposes. Both copiers would be depreci$-$ated on a straight$-$line basis over a period of three years. The corporate tax rate is $25\%.$ Assume that all operating cash flows and taxes are paid at the end of each year. a$.$computer the net present value of the new copier assuming the company goes ahead with the replacement decision. b$.$Using Excel, compute the IRR from investment in the new copier $($round off the nearest percentage$),$ assuming the company goes with the replacement decision. C$.$ What is the NPV from keeping the old copier? D$.$ Under the NPV method, which is the better option?
