Legend Service Center just purchased an automobile hoist for $32,100. The hoist has an 8-year life and an estimated salvage value of $3,200. Installation costs and freight charges were $3,500 and $800, respectively. Legend uses straight-line depreciation. The new hoist will be used to replace mufflers and tires on automobiles. Legend estimates that the new hoist will enable his mechanics to replace 5 extra mufflers per week. Each muffler sells for $74 installed. The cost of a muffler is $39, and the labor cost to install a muffler is $15. (a) Compute the cash payback period for the new hoist.

The following hypothetical production possibilities tables are for China and the United States. Assume that before specialization and trade the optimal product mix for China is alternative B and for the United States is alternative U. China Production Possibilities Product: A - B - C - D - E - F Apparel: 120,000 - 96,000 - 72,000 - 48,000 - 24,0000 Chemicals(tons): 0 - 24 - 48 - 72 - 96 - 120 U.S. Production Possibilities Product: R - S - T - U - V - W Apparel: 40,000 - 32,000 - 24,000 - 16,0000 - 8,0000 Chemicals(tons): 0 - 16 - 32 - 48 - 64 - 80a. Are comparative-cost conditions such that the two countries should specialize?
