Manufacturing overhead= $57,600
Step-by-step explanation:
To calculate the Conversion costs, we need to use the following formula:
Conversion costs= direct labor + manufacturing overhead
Now, if direct labor is 60% of conversion costs, then:
Conversion costs= direct labor / (1 - 0.4)
Conversion costs= 86,400 / 0.6
Conversion costs= $144,000
Finally, we determine the manufacturing overhead:
Manufacturing overhead= 144,000 - 86,400
Manufacturing overhead= $57,600
