Rossiter Fittings produces two models of pipe fittings for underwater lines. The two models (RF-12 and RF-25) have the following characteristics, as developed by a product cost analyst: Selling price per unit Variable cost per unit Expected units sold per year RF-12 $ 427 RF-25 $ 567 $ 347 $ 407 3,627 12,493 The total fixed costs per year for the company are $1,164,400. Required: a. What is the anticipated level of profits for the expected sales volumes? b. Assuming that the product mix is the same at the break-even point, compute the break-even point in units. c.

The head of marketing agrees that the total unit volume is likely to be as predicted by the cost analyst.
