Bubbly Waters currently sells 320 Class A spas, 470 Class C spas, and 220 deluxe model spas each year. The firm is considering adding a mid-class spa and expects that if it does, it can sell 395 units per year. However, if the new spa is added, Class A sales are expected to decline to 235 units while the Class C sales are expected to increase to 495. The sales of the deluxe model will not be affected. Class A spas sell for an average of $12,300 each. Class C spas are priced at $6,200 and the deluxe models sell for $17,200 each. The new mid-range spa will sell for $8,200. What annual sales figure should you use in your analysis?
