Winnebagel Corp. currently sells 35000 motor homes per year at $42400 each, and 18100 luxury motor coaches per year at $110500 each. The company wants to introduce a new portable camper to fill out its product line; it hopes to sell 16500 of these campers per year at $18400 each. An independent consultant has determined that if Winnebagel introduces the new campers, it should boost the sales of its existing motor homes by 6400 units per year, and reduce the sales of its motor coaches by 1900 units per year. What is the amount to use as the annual sales figure when evaluating this project?
