Direct Material: $1.80 ; Direct Labor: $2.00 ; variable manufacturing overhead: $.60 ; Fixed Manufacturing overhead: $4.35 ; Variable selling and manufacturing expenses:$1 ; Fixed selling and manufacturing expenses: $1.

The normal selling price is $23 per unit. The company's capacity is 10,300 units per month. An order has been received from a potential customer overseas for 1,800 units at a price of $20.00 per unit. This order would not affect regular sales.

1. If the order is accepted, by how much will monthly profits increase or decrease? (The order would not change the company's total fixed costs.)

2. Assume the company has 500 units of this product left over from last year that are inferior to the current model. The units must be sold through regular channels at reduced prices. What unit cost is relevant for establishing a minimum selling price for these units?
