Winnebagel Corp. currently sells 16,200 motor homes per year at $24,300 each, and 6,480 luxury motor coaches per year at $45,900 each. The company wants to introduce a new portable camper to fill out its product line; it hopes to sell 10,260 of these campers per year at $6,480 each. An independent consultant has determined that if Winnebagel introduces the new campers, it should boost the sales of its existing motor homes by 2,430 units per year, and reduce the sales of its motor coaches by 486 units per year.What is the amount to use as the annual sales figure when evaluating this project?
