Joseph Ethan, has asked you to assist in estimating maintenance costs. Together, you and Joseph determine that the single best cost driver for maintenance costs is machine hours. These data are from the previous fiscal year for maintenance costs and machine hours: N Month Maintenance Costs Machine Hours 1 $ 2,760 1,850 2 2,920 1,930 3 3,070 2,010 4 3,180 2,030 5 3,260 2,060 6 3,230 2,040 7 3,170 2,020 8 3,010 2,000 9 2,780 1,860 10 2,380 1,260 11 2,390 1,460 12 2,610 1,750 LON Required: 1.
