Appliance Possible inc. (AP) is a manufacturer of toaster ovens. To improve control over operations, the president of AP wants to begin using a flexible budgeting system, rather than use only the current master budget. The following data are available for AP's expected costs at production levels of 80,000,91,000, and 102,000 units. Prepare a flexible budget for each of the possible production levels: 80,000,91,000, and 102,000 units. (List vorlable costs before bxed costs.)
