Answer:
direct labor cost $ 1,99 overhead per dollar of labor
direct labor hours $ 16,12 overhead per labor hour
machine hours  $ 7,54 overhead per machine hour
Explanation:
We will sovle for the predeterminated overhead rate considering each of the three cost driver (activity base)
[tex]\frac{Cost\: Of \:Manufacturing \:Overhead}{Cost \:Driver}= Overhead \:Rate[/tex]
We divide the expected overhead over the cost driver chose by the company. In this case we have thre candidates:
direct labor cost:
822,000 / 414,000 =1,9855
direct labor hours
822,000 / 51,000 Â = 16,117647
machine hours
822,000 / 109,000 = 7,5412844
