Erber, Inc. produces men's neckties and dress socks. Manufacturing overhead is assigned
to production using an application rate based on direct labor hours.
(a.) For 2016, the company's cost accountant estimated that total overhead costs incurred
would be $184,500, and that a total of 24,600 direct labor hours would be worked.
Calculate the amount of overhead to be applied for each direct labor hour worked on a
production run.
(b.) A production run of 500 neckties required raw materials that cost $3,120, and 140
direct labor hours at a cost of $8.00 per hour. Calculate the cost of each necktie produced.
(c.) At the end of February 2016, 420 neckties made in the above production run had been
sold, and the rest were in ending inventory. Calculate the cost of the neckties sold that
would have been reported in the income statement and the cost included in the February
28, 2016, finished goods inventory.

Great Bay Co. manufactures cordless telephones. During 2016, total costs associated with
manufacturing 18,500 of the AB-2000 model (introduced this year) were as follows:
Raw materials
$195,175
Direct labor
115,625
Variable manufacturing overhead
85,100
Fixed manufacturing overhead

(a.) Calculate the cost per phone under both direct (or variable) costing and absorption
costing.
(b.) If 2,800 of these phones were in finished goods inventory at the end of 2016, by how
much and in what direction (higher or lower) would 2016 operating income be different
under direct (or variable) costing than under absorption costing?
(c.) Express the phone cost in a cost formula. What does this formula suggest the total
cost of making an additional 1,600 phones would be?

PlayCraft Co. manufactures toy boats. During 2016, total costs incurred in making 54,000
toy boats included $189,000 of fixed manufacturing overhead. The total absorption cost
per toy boat was $28.50.

(b.) The ending inventory of toy boats was 11,600 units higher at the end of 2016 than at
the beginning of the year. By how much and in what direction (higher or lower) would cost
of goods sold for 2016 be different under direct costing than under variable costing?
(c.) Express the toy boat cost in a cost formula. What does this formula suggest the total
cost of making an additional 5,800 toy boats would be?

Baja Industries has recently switched its method of applying manufacturing overhead from a
single predetermined overhead rate based on direct labor hours to activity-based costing
(ABC). Assume that the direct labor rate is $18.00 per hour and that there were no beginning
inventories. The following cost drivers and rates have been developed for allocating
manufacturing overhead costs:
Activity
Cost Driver
Material handling
Number of parts used
Assembly and inspection
Number of direct labor hours
Testing
Number of units tested
