Papa’s Pizza is considering replacement of its pizza oven with a new, more energy-efficient model. Information related to the old and new pizza ovens follows:

Old oven—original cost ..........$ 60,000

Old oven—book value ..........$ 50,000

Old oven—current market value ......$ 42,000

Old oven—annual operating cost .......$ 14,000

New oven—purchase price ........$ 75,000

New oven—installation cost ........$ 2,000

New oven—annual operating cost .....$ 6,000

The old oven had been purchased a year ago. Papa’s Pizza estimates that either oven has a remaining useful life of five years. At the end of five years, either oven would have a zero salvage value. Ignore the effect of income taxes and the time value of money.
