Compute the predetermined overhead allocation rates using machine hours as the allocation base for the Assembly Department and direct labor hours for the Packaging Department. Begin by selecting the formula to calculate the predetermined overhead (OH) allocation rate. Then enter the amounts to compute the allocation rate for each department. (Abbreviation used: Qty = quantity. Enter the allocation rates to the nearest cent.)
