CompDesk, Inc., makes a single model of an ergonomic desk (with chair) for computer usage. The desk is manufactured in building 1, and the chair is manufactured in building 2. Monthly capacities and production levels are as follows.

	Building 1 (Desks)	Building 2 (Chairs)
Monthly capacity	400	500
Monthly production	400	400

The company will sell a desk only with a chair and can sell 500 desks per month. The units (desk with chair) sell for $276 each and have a variable cost of $117 each.

Required:

1. CompDesks production supervisors state they could increase building 1s capacity by 100 desks per month by producing desks on the weekend. Producing on the weekend would not affect the sales price. Variable cost per unit would increase by $17 for those produced on the weekend because of the premium paid to labor. Fixed costs would also increase by $18,400 per month. Calculate the differential operating profit (loss).

2. Independent of the situation in requirement (b), CompDesk could add additional equipment and workers to building 1, which would increase its capacity by 100 desks per month. This would not affect the sales price or variable cost per unit but would increase fixed costs by $14,200 per month. Calculate the differential operating profit (loss).
