Answer and Explanation:
The computation is shown below:
a. For the manufacturing overhead rate for the year
As we know that
Manufacturing overhead rate = Estimated overhead cost ÷ machine usage
= $327,080 ÷ 125,800 hours
= $2.60 per hour
b. Now the amount of under- or over applied overhead is
= Applied overhead - actual overhead
where,
Applied overhead is
= 130,500 hours × $2.60
= $339,300
And, the actual overhead is $349,600
So, the under overhead applied is $10,300
3. And, the journal entry is
Cost of goods sold $10,300
To Manufacturing overhead $10,300
(Being the under applied overhead is recorded)
