Answer:
A. $400,000
B. $6 per machine hour
Step-by-step explanation:
A. The computation of budgeted variable manufacturing overhead is shown below:-
Budgeted variable overhead cost = Four quarters × Variable manufacturing overhead rate
= (35,000 + 20,000 + 15,000 + 30,000) × $4
= 100,000 × $4
= $400,000
B. The computation of predetermined overhead rate is shown below:-
Predetermined rate = Variable manufacturing overhead rate + Fixed manufacturing overhead) ÷ Total machine hours
= $400,000 + ($50,000 × $4) ÷ 100,000
= $6 per machine hour
