Practical capacity for the plant is defined as $55,200$ machine hours per year, which represents $27,600$ units of output. Annual budgeted fixed factory overhead costs are $$276,000$ and the budgeted variable factory overhead cost rate is $$3\mathrm{.}70$ per unit. Factory overhead costs are applied on the basis of standard machine hours allowed for units produced. Budgeted and actual output for the year was $21,500$ units, which took $44,200$ machine hours. Actual fixed factory overhead costs for the year amounted to $$264,800$ while the actual variable overhead cost per unit was $$3\mathrm{.}60.$
