Winnebagel Corp. currently sells 37200 motor homes per year at $56700 each, and 12300 luxury motor coaches per year at $105200 each. The company wants to introduce a new portable camper to fill out its product line; it hopes to sell 18900 of these campers per year at $18500 each. An independent consultant has determined that if Winnebagel introduces the new campers, it should boost the sales of its existing motor homes by 5800 units per year, and reduce the sales of its motor coaches by 1100 units per year. What is the amount to use as the annual sales figure when evaluating this project?
