Answer:
The annual capacity is 85000 units. If order is accepted of 12000 units the company will be able to sell only 73000 units (instead of 78000).
Explanation:
Current Net Income calculation and New Net Income calculation are atteched in the archive.
Contribution gain on special order – 12000 units x ($105-$90) = $180,000
(-) Contribution lost of normal sale – (78000 units – 73000 units) x ($120-$90) = $150000
Net INCREASE = 180000 – 150000 = $30,000
