Answer and Explanation:
1.
The direct labor overhead rate using the direct labor hours is shown below:-
Direct labor overhead rate = Total overheads ÷ Direct labor hours
= $220,800 ÷ 1,725
= $128
b. The machine hour overhead rate using the machine hours is
= Total overhead ÷ Machine hours
= $220,800 ÷ 4,600
= $48
2.
The factory overhead costs using direct labor hour is
Particulars Automobile Valve Wheels Total
bumpers covers
Direct labor
hours 730 480 515
Overhead rate $128 $128 $128
Total $ 93,440 $61,440 $65,920 $220,800
For determining the total overhead we simply multiply the direct labor hours with overhead rate.
The factory overhead costs using machine hour is
Particulars Automobile Valve Wheels Total
bumpers covers
Machine hours 1,970 1,270 1,360
Overhead rate $48 $48 $48
Total overhead $94,560 $60,960 $65,280 $220,800
For determining the total overhead we simply multiply the machine hours with overhead rate.
