Johnny Lee Inc. produces a line of small gasoline-poweredengines that can be used in a variety of residential machines,ranging from different types of lawnmowers, to snowblowers, togarden tools (such as tillers and weed-whackers). The basic productline consists of three different models, each meant to fill theneeds of a different market. Assume you are the cost accountant forthis company and that you have been asked by the owner of thecompany to construct a flexible budget for factory overhead costs,which seem to be growing faster than revenues. Currently, thecompany uses machine hours (MHs) as the basis for assigning bothvariable and fixed factory overhead costs to products.

Within the relevant range of output, you determine that thefollowing factory fixed overhead costs per month should occur:engineering support, $16,100; insurance on the manufacturingfacility, $6,100; property taxes on the manufacturing facility,$13,100; depreciation on manufacturing equipment, $14,900; andindirect labor costs of supervisory salaries, $15,900, setup labor,$3,500, and materials handling, $3,600. Variable factory overheadcosts are budgeted at $76.00 per machine hour, as follows:electricity, $19.00; indirect materials for Material A of $12.00and for Material B of $15.00; indirect labor—maintenance, $17.00;and production-related supplies, $13.00.

Required:

1. Prepare a flexible budget for Johnny Lee for each of thefollowing monthly levels of machine hours: (a) 5,100, (b) 6,100,and (c) 7,100.

2. Generate an equation to represent, within the relevant range,the factory overhead costs per month for Johnny Lee. Use thisequation to estimate monthly total overhead cost for machine hoursof 4,100 to 7,100, in increments of 500.
