$\frac{Cost\: Of \:Manufacturing \:Overhead}{Cost \:Driver}= Overhead \:Rate$

the expected overhead wil be distribute over the cost driver which, in this case, is machine hours:

840,000 / 70,000 = $12

each machine hours will generate 12 dollar of overhead

b) applied overhead:

67,000 hours x $12 overheead per hour = 804,000

c) actial overhead
