Good day, I could use a little assistance solving PARTS A, B, & C:

Chizzelz Company produces "collapse-proof" rod and reel cases. In preparing the current budget for the year, Chizzelz estimates a total of $400,000 in direct materials cost, $300,000 in direct labor cost, and $300,000 in manufacturing overhead costs. Since the manufacturing process is highly automated, the company uses machine hours as the overhead application base. Estimated machine hours total 12,000. At the end of the period, Chizzelz reported actual results as follows: direct materials cost of $410,000, direct labor cost of $250,000, manufacturing overhead cost $310,000, and machine hours used 12,500.

Required:

a. What is Chizzelz predetermined overhead rate for the year?

b. How much manufacturing overhead did Chisels apply to jobs during the year?

c. If over- or underapplied overhead is closed to Cost of Goods Sold, what is the balance in the Manufacturing Overhead account after the adjustment?
