Points Vargis Corporation has a machining capacity of 217,000 hours per year. Utilization of capacity is normally 85%; it has been as low as 30% and as high as 90%. An analysis of the accounting records revealed the following selected costs: At a 90% Utilization Rate At a 30% Utilization Rate Cost A: Total Per hour 6969 $ 457,000 $ 7.2 Cost B: Total ? Per hour 69 $ 12.5 Cost C: Total $ Per hour 69 69 765,000 $ 17 69 69 69 $ 457,000 ? 1,961,000 12.5 1,347,000 69 69 $ 9.09 Vargis uses the high-low method to analyze cost behavior. Required: A. Classify each of the costs as being either variable, fixed, or semivariable. B. Calculate amounts for the two unknowns (indicated by "?") in the preceding table. C. Calculate the total amount that Vargis would expect at a 85% utilization rate for Cost A, Cost B, and Cost C. D. Develop an equation that Vargis can use to predict total cost for any level of hours within its range of operation. 223 m
