Bubbly Waters currently sells 510 Class A spas, 660 Class C spas, and 410 deluxe model spas each year. The firm is considering adding a mid-class spa and expects that if it does, it can sell 585 units per year. However, if the new spa is added, Class A sales are expected to decline to 330 units while the Class C sales are expected to increase to 685. The sales of the deluxe model will not be affected. Class A spas sell for an average of $16,100 each. Class C spas are priced at $8,100 and the deluxe models sell for $19,100 each. The new mid-range spa will sell for $10,100. What annual sales figure should you use in your analysis?
