Winnebagel Corp. currently sells 20200 motor homes per year at $54600 each, and 12800 luxury motor coaches per year at $93100 each. The company wants to introduce a new portable camper to fill out its product line; it hopes to sell 21200 of these campers per year at $15700 each. An independent consultant has determined that if Winnebagel introduces the new campers, it should boost the sales of its existing motor homes by 7900 units per year, and reduce the sales of its motor coaches by 900 units per year. What is the amount to use as the annual sales figure when evaluating this project?
