Final answer:
To compute the customer margin using traditional costing based on machine hours, calculate the total cost of labor and machine and subtract it from the revenue obtained.
Step-by-step explanation:
To compute the customer margin using traditional costing based on machine hours, we need to calculate the total cost of the jobs using the traditional costing method and then subtract the total cost from the revenue obtained.
First, we calculate the total cost of labor and machine based on the given information. Labor cost is $24 per hour, and machine cost is $24 per hour as well. Each job requires 1.65 hours of labor and 1.65 hours of machine, resulting in a total cost of $60.36 for labor and machine per job. Multiply this cost by the total number of jobs (37) to get the total cost of jobs, which is $2,232.12.
Next, we subtract the total cost of jobs from the revenue obtained, which is $3,731. The customer margin is given by revenue minus total cost of jobs, which equals $3,731 - $2,232.12 = $1,498.88.
