Answer:
$600
Explanation:
The computation of the total manufacturing overhead allocated is
= Assembly department + sanding department
where,
Assembly department = Departmental overhead rate ×  machine hour
                   = $60 × 9
                   = $540
And, the sanding department is
= Departmental overhead rate × direct labor hour
= $15 × 4
= $60
So, the total manufacturing overhead allocated is
= $540 + $60
= $600
