Lupo Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on machine-hours. The company based its predetermined overhead rate for the current year on the following data:
Total machine-hours 30,300Total fixed manufacturing overhead cost $ 575,700Variable manufacturing overhead per machine-hour $ 4.00Recently, Job T687 was completed with the following characteristics:
Number of units in the job 10Total machine-hours 30Direct materials $ 730Direct labor cost $ 1,460
The total job cost for Job T687 is closest to:

$2,880

Explanation:

Given that,

Total machine-hours = 30,300

Total fixed manufacturing overhead cost = $ 575,700

Variable manufacturing overhead per machine-hour = $ 4.00

For Job T687:

Number of units in the job = 10

Total machine-hours = 30

Direct materials = $730

Direct labor cost = $1,460

Total variable overhead estimated:

= Variable manufacturing overhead per machine-hour × Total machine-hours

= $4 × 30,300

= $121,200

Total overhead estimated:

= Total variable overhead estimated + Total fixed overhead estimated

= $121,200 + $575,700

= $696,900

Predetermined overhead rate:

= Total overhead estimated ÷ Total machine-hours

= $696,900 ÷  30,300

= $23 per machine hour

Total overhead applied:

= predetermined overhead rate × Total machine hours for Job T687

= $23 × 30

= $690

Total job cost:

= Direct material + Direct labor + Total overhead

= $730 + $1,460 + $690

= $2,880
