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 2 HON Book 5 6 Maintenance Costs $ 2,600 2,760 2,910 3,020 3, 100 3,070 3,010 2,850 2,620 2,220 2,230 2,450 Machine Home 1690 10 1 850 1 70 900 80 1860 1840 1,700 1. 100 1 300 1,590 rint B 9 10 11 12 rences Required: 1.
