Specifically, she wants to know how much support cost is fixed and how much is variable. The following data are the only records available: Month Machine Hours Support Costs May 900 $ 9,200 June 1,350 12,500 July 990 8,000 August 1,250 11,000 September 1,800 14,000 Required: 1. Find monthly fixed support cost and the variable support cost per machine hour by the high-low method. 2. Explain how our analysis for Requirement 1 would change if new October data were received and machine hours were 1,700 and support costs were $15,800. 3. A least-squares regression analysis gave the following output: Regression equation: Y = $3,355 + $6.10X
