Final answer:
To calculate the total job cost for Job M242, we need to consider the direct materials, direct labor, and overhead costs. The total job cost for Job M242 is $3,605.
Step-by-step explanation:
To calculate the total job cost for Job M242, we need to consider the direct materials, direct labor, and overhead costs. In this case, we have the following information:
Direct materials: $725
Direct labor cost: $1,680
Machine-hours: 60
Since B Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on machine-hours, we can calculate the overhead cost by multiplying the machine-hours by the predetermined overhead rate. Let's assume the predetermined overhead rate is $20 per machine-hour. Then the overhead cost would be $20 x 60 machine-hours = $1,200.
Finally, we can calculate the total job cost by adding the direct materials, direct labor, and overhead costs together:
Total job cost = Direct materials + Direct labor + Overhead cost
Total job cost = $725 + $1,680 + $1,200 = $3,605.
