Final answer:
The manufacturing overhead rate is calculated by dividing the total estimated overhead costs by the estimated machine hours. For Coronado Company, that rate is $2.30 per machine hour.
Step-by-step explanation:
To compute the manufacturing overhead rate for the year, we need to divide the total estimated overhead costs by the estimated machine hours used. The formula to calculate the overhead rate is Total Estimated Overhead Costs / Estimated Machine Hours. Using the information given:
Total Estimated Overhead Costs: $294,400
Estimated Machine Hours: 128,000 hours
Now, perform the calculation:
$294,400 / 128,000 hours = $2.30 per machine hour
Thus, the manufacturing overhead rate is $2.30 per machine hour.
