Answer:
$8.20/Direct Labor hours
Explanation:
Cost of performing engine repair work = Shop and repair equipment depreciation + Shop supervisor salaries + Shop property taxes + Shop supplies
Cost of performing engine repair work = $40,000 + $133,000  + $22,000 + $10,000
Cost of performing engine repair work = $205,000
Direct Labor Hours = Direct Labor/Direct Labor rate
Direct Labor Hours = 500,000/$20 per hour
Direct Labor Hours = 25,000 hours
Predetermined shop overhead rate per direct labor hour = $205,000 / 25,000 Hours = $8.20/Direct Labor hours

Marginal cost= $20
Therefore the marginal cost of producing an additional unit of output is $20
