(Calculation offlexible budget) The monthly overhead cost formula for Issac Cor¬ poration is currently estimated as $36,000 T $42X, where X represents machine hours. Company management believes operations will expand into a new relevant range in the upcoming year. Fixed costs are expected to rise to $54,000 for any activity level above 5,000 machine hours, and the variable cost rate is expected to drop at 6,000 machine hours by $6 per machine hour due to volume purchasing.

a. Prepare a flexible budget for the 4,500, 5,500, and 6,500 machine hour levels.
