Answer:
$1,350,000
Explanation:
Calculation to determine the total manufacturing overhead costs
First step is to calculate the Variable overhead
Variable overhead= $720,000 + $180,000 +$150,000
Variable overhead=$1,050,000
Second step is to calculate Unitary variable overhead
Unitary variable overhead= $1,050,000/50,000
Unitary variable overhead= 21
Now let calculate the total manufacturing overhead costs
For 60,000 units:
Total Manufacturing Overhead Costs = 21*60,000 + 90,000
Total Manufacturing Overhead Costs= $1,350,000
Therefore the total manufacturing overhead costs is $1,350,000
