Cool Comfort currently sells 300 Class A spas, 450 Class C spas, and 200 deluxe model spas each year. The firm is considering adding a mid-class spa and expects that, if it does, it can sell 375 of them. However, if the new spa is added, Class A sales are expected to decline to 225 units while the Class C sales are expected to decline to 200. The sales of the deluxe model will not be affected. Class A spas sell for an average of $12,000 each. Class C spas are priced at $6,000 and the deluxe model sells for $17,000 each. The new mid-range spa will sell for $8,000.
