Answer:
b) 168,000 direct labor hours
Step-by-step explanation:
The computation of the actual level of activity achieved is shown below:
= (Total budgeted manufacturing cost - budgeted monthly manufacturing overhead cost) ÷ (Rate per direct labor hour)
= ($1,044,000 - $540,000) ÷ ($3)
= $504,000 ÷ $3
= 168,000 direct labor hours
Simply we deduct the budgeted monthly manufacturing overhead cost from the total budgeted manufacturing cost and then divide it by the rate per direct labor hour so that the accurate direct labor hours could be computed
