Manchester Corporation is considering the purchase of a new boiler for $350,000. The firm's old boiler has a book value of $85,000, but has a current market value of $60,000. It is being depreciated on a straight-line basis at the rate of $21,250 per year (and, as result, will be fully depreciated in 4 years). Its salvage value is expected to be $20,000 at the end of 5 years. The new boiler will require modifications costing $15,000. The new boiler will be depreciated using the 5-year MACRS schedule. It is expected to have a salvage value of $80,000 at the end of 5 years, at which time it will be sold. The new boiler is expected to increase revenues by $63,000 for each of the next 5 years. In addition, operating expenses will be reduced by $32,000 for each of the next five years. Manchester's marginal tax rate is 40 percent. Its marginal cost of capital is 15 percent.

Chunkendales' Beef has a 12% cost of capital, and has generated the following information on two projects:
