What is the formula to calculate Actual Overhead when these are the only numbers that I am given?

Actual machine hours 17,200
Estimated machine hours 18,000
Overhead application rate $5.00
Actual overhead ?
Estimated overhead $90,000
Applied overhead $86,000
Over- (under-) applied
Overhead $6,500

I can't seem to figure out this problem in my accounting homework. I have all the rest done but this one I just can't seem to wrap my head around. Can someone help with the formulas for the questions asked?


Computations using a job order system
General Corporation employs a job order cost system. On May 1 the following balances were extracted from the general ledger;

Work in process $ 35,200
Finished goods 86,900
Cost of goods sold 128,700

Work in Process consisted of two jobs, no. 101 ($20,400) and no. 103 ($14,800). During May, direct materials requisitioned from the storeroom amounted to $96,500, and direct labor incurred totaled $114,500. These figures are subdivided as follows:

Direct Materials Direct Labor
Job No. Amount Job No. Amount
101 $5,000 101 $7,800
115 19,500 103 20,800
116 36,200 115 42,000
Other 35,800 116 18,000
$96,500 Other 25,900
$114,500



Job no. 115 was the only job in process at the end of the month. Job no. 101 and three "other" jobs were sold during May at a profit of 20% of cost. The "other" jobs contained material and labor charges of $21,000 and $17,400, respectively.

General applies overhead daily at the rate of 150% of direct labor cost as labor summaries are posted to job orders. The firm's fiscal year ends on May 31.

Instructions:
a. Compute the total overhead applied to production during May.
b. Compute the cost of the ending work in process inventory.
c. Compute the cost of jobs completed during May.
d. Compute the cost of goods sold for the year ended May 31.

My book is no help. I have read it over and over again to no avail. It is an online class and my instructor isn't much help.

I have not figured out any of the questions posted. Still trying. I was meaning that I had figured out the other parts to that particular question.

Any help would be appreciated. I am struggling with these parts of this assignment. I have asked my instructor for guidance on them. No reply from him thus far.
