Chapter 1, Problem 23DQ

I need help with this solution and general accounting question

Cozy Retreats currently sells 420 Standard hot tubs, 580 Luxury hot tubs, and 190 Premium model hot tubs each year. The firm is considering adding a Comfort model hot tub and expects that, if it does, it can sell 340 of them. However, if the new hot tub is added, standard sales are expected to decline to 290 units while Luxury sales are expected to decline to 310. The sales of the Premium model will not be affected. Standard hot tubs sell for an average of $8,900 each. Luxury hot tubs are priced at $14,500 and the Premium model sells for $22,000 each. The new Comfort model will sell for $12,300. What is the value of erosion?
