A restaurant operator wishes to choose between two alternative roll-in storage units. Machine A will cost $9,000 and have a trade-in value at the end of its five-year life of $1,500. Machine B will cost $8,500 and at the end of its five-year life will have a trade-in value of $700. As- sume straight-line depreciation. Investment in the machine will mean that a part-time kitchen worker will not be required, and there will be an annual wage saving of $9,600. The following will be the operating costs, excluding depreciation, for each machine, for each of the five years.
