Paz Inc. manufactures a product that contains a small motor. The company has always purchased this motor from a supplier for $56 each. Paz recently upgraded its own manufacturing capabilities and now has enough excess capacity (including trained workers) to begin manufacturing the motor instead of buying it. The company prepared the following per unit cost projections of making the motor, assuming that overhead is allocated to the part at the normal predetermined overhead rate of 150% of direct labor cost.

Direct materials	$20.0
Direct labor	22.4
Overhead (fixed and variable)	33.6
Total	$76.0

The required volume of output to produce the motors will not require any incremental fixed overhead. Incremental variable overhead cost is $22.4 per motor. What is the effect on income if Paz decides to make the motors?

	Income will decrease by $8.8 per unit.
	Income will increase by $8.8 per unit.
