1. Total cost:
Direct material (10,000 units x $36)…………...
$ 360,000
2. The cost of the year-end inventory of 400 units (10,000 units produced – 9,600 units
sold) is computed as follows:
Absorption

3. The total costs would be allocated between the current period’s operating income
statement and the year-end inventory on the balance sheet. Thus:

1. Reported operating income will be higher under absorption costing, because
2. a. Variable costing: Total contribution during first 10 months is equal to the fixed
costs plus profit for that period.
Projected total sales for the year are 119,000 units (100,000 in first 10 months
plus 19,000 units in last 2 months). We can compute projected operating income
for the year as follows. (There are no selling and administrative costs.)
b. Absorption costing: The gross margin for the first 10 months is $300,000. Notice
that operating income and gross margin are the same, since there are no selling
or administrative expenses. Therefore, during the first 10 months:

PROBLEM 8-37 (CONTINUED)
Projected sales for the year are 119,000 units, so we can compute the projected
gross margin for the year as follows:
Projected gross margin ($3 119,000) ..............................................

3. The advantages and disadvantages of variable and absorption costing are
summarized as follows:
