Answer:
125%
Explanation:
The computation of overhead rate and percentage of direct labor costs is given below:-
The Predetermined rate is
= (Manufacturing Overhead ÷ total number of direct labor) × 100
where,
Overhead manufacturing
= $3,180 - ($520 + $320 + $420 + $620)
= $3,180 - $1,880
= $1,300
And, The total number of direct labor
= $420 + $620
= $1,040
So, the Predetermined rate
= ($1,300 ÷ $1,040) × 100
= 125%
