his first year of operations: Rent $9200 Depreciation on equipment $7000 Wages $16400 Motor oil $2.00 per quart. He estimates that each oil change will
require 5 quarts of oil. Oil filters will cost $3.00 each. He must also pay the Fast n%u2019 Clean Corporation a franchise fee of $1.10 per oil change since
he will operate the business as a franchise. In addition utility costs are expected to behave in relation to the number of oil changes as follows:

Number of oil changes Utility cost

4000 $ 6000

6000 $ 7300

9000 $ 9600

12000 $ 12600

14000 $ 15000
