Answer:
The predetermined overhead rate is $5.5 per hour
Explanation:
The formula to compute the predetermined overhead rate is shown below
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated direct labor-hours)
where,
Total estimated manufacturing overhead = Fixed manufacturing overhead + variable manufacturing overhead
= $90,000 + $3.70 × 50,000 direct labor hours
= $90,000 + $185,000
= $275,000
And, the direct labor hour is 50,000
Now put these values to the above formula
So, the value would equal to
= $275,000 ÷ 50,000 direct labor hours
= $5.5 per hour
