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
