Exercise 3-14 (20 minutes)
1. The estimated total manufacturing overhead cost is computed as fol-
lows:
Y = $650,000 + ($3.00 per MH)(100,000 MHs)
Estimated fixed manufacturing overhead ...................
$650,000
Estimated variable manufacturing overhead: $3.00
per MH × 100,000 MHs .........................................
300,000
Estimated total manufacturing overhead cost ............
$950,000
The predetermined overhead rate is computed as follows:
Estimated total manufacturing overhead .......
$950,000
÷ Estimated total machine-hours (MHs) ........
100,000
MHs
= Predetermined overhead rate ....................
$9.50
per MH
2. Total manufacturing cost assigned to Job 400:
Direct materials .......................................................
$ 450
Direct labor .............................................................
210
Manufacturing overhead applied ($9.50 per MH × 40
MHs) ....................................................................
380
Total manufacturing cost ..........................................
$1,040
3. Computing underapplied/overapplied overhead:
Actual manufacturing overhead (a) ..........
$1,350,000
Actual machine-hours ..............................
146,000
× Predetermined overhead rate ...............
$9.50
= Manufacturing overhead applied (b) .....
$1,387,000
Overapplied overhead (a) – (b) ................
$ (37,000)
The closing entry would decrease cost of goods sold by $37,000 and in-
crease net operating income by $37,000.

3. Yes; if some jobs require a large amount of machine time and a small
amount of labor time, they would be charged substantially less overhead

2d. Because the company has no beginning or ending inventories and
only Jobs D-70 and C-200 were started, completed, and sold during
the year, the cost of goods sold is equal to the sum of the manufac-
turing costs assigned to both jobs of $3,070,000 (=$1,652,000 +
$1,418,000).
3. The plantwide and departmental approaches for applying manufacturing
overhead costs to products produce identical cost of goods sold figures.
However, these two approaches lead to different bid prices for Jobs D-
Exercise 3-18 (30 minutes)
1. The predetermined overhead rate is computed as follows:
Y = $128,000 + $0.80 per MH × 80,000 MHs
Estimated fixed manufacturing overhead ..................
$128,000
Estimated variable manufacturing overhead
$0.80 per MH × 80,000 MHs .................................
64,000
Estimated total manufacturing overhead cost ............
$192,000
The predetermined overhead rate is computed as follows:
Estimated total manufacturing overhead ........
$192,000
÷ Estimated total machine-hours ..................

= Predetermined overhead rate ....................
$2.40
per MH
2. The amount of overhead cost applied to Work in Process for the year
would be: 75,000 machine-hours × $2.40 per machine-hour =
$180,000. This amount is shown in entry (a) below:
