Sorrento Products uses a job costing accounting system for its manufacturing costs. A predetermined overhead rate based on machine$-$hours is used to apply overhead to individual jobs. An estimate of overhead costs at different volumes was prepared for the current year as follows.

Machine$-$hours $199,500213,000259,500$

Variable overhead costs $ $758,100$ $ $809,400$ $ $986,100$

Fixed overhead costs $1,810,5001,810,5001,810,500$

Total overhead $ $2,568,600$ $ $2,619,900$ $ $2,796,600$

The expected volume is $213,000$ machine$-$hours for the entire year. The following information is for March, when Jobs $302$ and $304$ were completed:

Required:

Compute the predetermined overhead rate $($combined fixed and variable$)$ to be used to apply overhead to individual jobs during the year.

$($Note: Regardless of your answer to requirement $[$a$],$ assume that the predetermined overhead rate is $$13\mathrm{.}30$ per machine$-$hour. Use this amount in answering requirements $[$b$]$ through $[$f$],$ as needed.$)$

Compute the total cost of Job $302$ when it is finished.

How much of factory overhead cost was applied to Job $305$ during March?

What total amount of overhead was applied to jobs during March?

Compute actual factory overhead incurred during March.

At the end of the year, Sorrento Products had the following account balances:

Balance

Overapplied overhead $ $1,706,000$

Work$-$in$-$process inventory $2,654,300$

Finished goods inventory $965,200$

Cost of goods sold $20,510,500$

Show the overapplied overhead effect on the account balances $($final balances after allocation$)$ in the following table.
