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 Maintenance Costs Machine Hours 1 $ 2,620 1,710 2 2,780 1,790 3 2,930 1,870 4 3,040 1,890 5 3,120 1,920 6 3,090 1,900 7 3,030 1,880 8 2,870 1,860 9 2,640 1,720 10 2,240 1,120 11 2,250 1,320 12 2,470 1,610 Required: 1. What is the cost equation for maintenance costs using the high-low method? 2. Calculate the mean absolute percentage error (MAPE) for the cost equation you developed in requirement 1. O Answer is complete but not entirely correct. Complete this question by entering your answers in the tabs below.
