cost of the component according to the company's cost accounting system is given as
follows:
Direct materials
$8.80
Direct labor
5.80
Variable manufacturing overhead

Item N29 is used by Tyner Corporation to make one of its products. A total of 11,000 units
of this Item are produced and used every year. The company's Accounting Department
reports the following costs of producing the Item at this level of activity:
Per Unit
Direct materials
$5.90
Direct labor
1.70
Variable manufacturing overhead
5.40
Supervisor’s salary
2.60
Depreciation of special equipment
3.20
Allocated general overhead
3.30
An outside supplier has offered to make the Item and sell it to the company for $21.20
each. If this offer is accepted, the supervisor's salary and all of the variable costs,
including the direct labor, can be avoided. The special equipment used to make the Item
was purchased many years ago and has no salvage value or other use. The allocated
general overhead represents fixed costs of the entire company, none of which would be
avoided if the Item were purchased instead of produced internally. In addition, the space
used to make Item N29 could be used to make more of one of the company's other
products, generating an additional segment margin of $29,000 per year for that product.
What would be the impact on the company's overall net operating income of buying Item
N29 from the outside supplier?

Management has expressed special concern with the regional market because of the
extremely poor return on sales. This market was entered a year ago because of excess
capacity. It was originally believed that the return on sales would improve with time, but
after a year, no noticeable improvement can be seen from the results as reported in the
above quarterly statement. In attempting to decide whether to eliminate the regional
market, the following information has been gathered:
