Andretti Company has a single product called a Dak. The company normally produces and sells 60,000 Daks each year at a selling price of $32 per unit. The companys unit costs at this level of activity are given below:

Direct materials	$	10.00
Direct labor		4.50

Fixed manufacturing overhead		5.00	($300,000 total)
Variable selling expenses		1.20
Fixed selling expenses		3.50	($210,000 total)
Total cost per unit	$	26.50

A number of questions relating to the production and sale of Daks follow. Each question is independent.

Required:

1-a. Assume that Andretti Company has sufficient capacity to produce 90,000 Daks each year without any increase in fixed manufacturing overhead costs. The company could increase its sales by 25% above the present 60,000 units each year if it were willing to increase the fixed selling expenses by $80,000. Calculate the incremental net operating income.

Increased sales in units
Contribution margin per unit
Incremental contribution margin
Less added fixed selling expense
Incremental net operating income	$0
