Setup overhead costs consist of some costs that are variable and some costs that are fixed with respect to the number of setup-hours. The following information pertains to June 2015:
Actual Static-budget Amounts Amounts
Units produced and sold 15,000 11,250

Setup-hours per batch 5 5.25
Variable overhead cost per setup-hour $40 $38
Total fixed setup overhead costs $12,000 $9,975
