Answer:
$27.2
Step-by-step explanation:
First we have to calculate the total estimated manufacturing overheads which shall be determined as follows:
Estimated total manufacturing overheads=Variable manufacturing overhead+ Fixed manufacturing overheads
Variable manufacturing overhead=Estimated labour hours*manufacturing overhead per labour hour
=75,000*$10.70=$802,500
Fixed manufacturing overheads=$1,237,500
Estimated total manufacturing overheads=$802,50+$1,237,500
=$2,040,000
Now we will compute the predetermined overhead rate which shall be determined using the following formula:
Predetermined overhead rate=Estimated total manufacturing overheads/Estimated labour hours
Predetermined overhead rate=$2,040,000/75,000=$27.2
