Ethan Manufacturing Incorporated produces floor mats for automobiles. The owner, 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: Month 1 3 Maintenance Costs $ 2,600 2,760 2,910 3,020 46 3,100 ad 3,070 3,010 Bond 2,850 2,620 2,220 2,230 2,450 Machine Hours 1,690 1,770 1,850 1,870 1,900 od 200 1,880 1000 1,860 1,840 od 1,700 1,100 1,300 1,590 9 10 11 12 Required: 1.
