Answer :
Overhead applied per unit = $557.61
Explanation :
As per the data given in the question,
Particulars A B C=A ÷B D C ×D
Activity cost Estimated Total expected Activity Product A4 Product A4
Pool OH cost Activities Rate Expected activities total OH cost
Labor related $163,058 $7,800 20.90 4,200 $87,780
Machine setup $10,550 $1,500 7.03 800 $5,624
Order size $499,527 $8,700 57.42 4,200 $241,164
Total overhead cost = $334,568
Activity rate = Estimated OH cost ÷ Total expected activity
Product A4 overhead = Product A4 expected activity ×activity rate
Overhead applied per unit = Total overhead applied ÷ Expected production of A4
= $334,568 ÷ 600 units
=$557.61
