Estimate how much of the 5246,660 of overhead cost in July was maintenance cost. (Hint To do this, first determine how much of the $246 660 consisted of utilities and supervisory salaries. Think about the behaviour of variable and fixed costs within the relevant range) (Do not round Intermediate calculations.) 2. Using the high-low mlshod, estimate a cost formula for maintenance (Do not round your intermediate calculations. Round the "Variable cost per unit" to 2 decimal places.)
