At the beginning of the year, Smith Company budgeted overhead of $129,600 as well as 13,500 direct labor hours. During the year, Job K456 was completed with the following information: direct materials cost, $2,750; direct labor cost, $5,355. The average wage for Smith Company employees is $17 per hour. By the end of the year, 18,100 direct labor hours had actually been worked, and Smith incurred the following actual overhead costs for the year:
Equipment lease $ 6,800
Depreciation on building 19,340
Indirect labor 90,400
Utilities 14,560
Other overhead 41,400
Required:
1. Calculate the overhead rate for the year.
2. Calculate the total cost of Job K456.
3. Prepare the journal entries to record actual overhead and to apply overhead to production for the year.
4. Is overhead overapplied or underapplied? By how much?
5. Assuming that the normal cost of goods sold for the year is $635,600, what is the adjusted cost of goods sold?

4. Over applied overhead= $1,260

5. $634,340

Explanation:

1) Calculation for the overhead rate for the year

Using this formula

Overhead rate = Estimated overhead/Estimated hour

Let plug in the formula

Overhead rate = 129600/13500

Overhead rate = 9.60 per hour

2) Calculation for the total cost of Job K456

Total cost of Job K456

(5355/17*9.60)

3) Preparation of the journal entries to record actual overhead and to apply overhead to production for the year.

(Being To record actual overhead)

Work in process (18100*9.6)173760

Manufacturing overhead 173760

(To record applied overhead)

4) Calculation for whether overhead is overapplied or underapplied

Over applied overhead = 173760-172500

Over applied overhead= $1260

5) Calculation for the adjusted cost of goods sold

Adjusted cost of goods sold = 635600-1260

Adjusted cost of goods sold= $634340

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
