Answer:
$1,068,000
Step-by-step explanation:
The computation of the total manufacturing overhead cost should be
Total variable manufacturing overhead for 50,000 machine hours is
= Indirect labor + Machine supplies +Indirect materials
= 630,000+90,000+120,000
= $840,000
Now
Variable manufacturing overhead per machine hour is
= Total variable manufacturing overhead cost ÷ Number of machine hours
= $840,000 ÷ 50,000
= $16.80
And,
Total variable manufacturing overhead for 60,000 machine hours
= Variable manufacturing overhead per machine hour × 60,000
= $16.80 × 60,000
= $1,008,000
Now the total manufacturing overhead cost should be
= 1,008,000 + 60,000
= $1,068,000
