Answer:
$14.71
Explanation:
The computation of the predetermined overhead rate is shown below:
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated machine hours)
where,
Total estimated manufacturing overhead is
= Estimated total fixed overhead manufacturing overhead + Estimated variable manufacturing overhead × estimated machine hours
= $838,750 + $3.20 × 72,900 machine hours
= $838,750 + $233,280
= $1,072,030
So, the predetermined overhead rate is
= $1,072,030 ÷ 72,900 machine hours
= $14.71
