PROBLEM 4-21 Basic Cost-Volume-Profit Analysis; Graphing [LO1, LO2, LO4, LO5] The Tops national chain of shirt stores carry many styles of shirts that are all sold at the same price.

The following table contains cost and revenue data for the Bradbury store. These data are typical of the company's many outlets: Tops is a fairly new company. The company has asked you, as a member of its planning group, to assist in some basic analysis of its stores and company policies. Required: 1. Calculate the annual break-even point in dollar sales and in unit sales for the Bradbury store. 2. Prepare a CVP graph showing cost and revenue data for the Bradbury store from 0 shirts up to 30,000 shirts sold each year. Clearly indicate the break-even point on the graph. 3. If 19,000 shirts are sold in a year, what will be the Bradbury store's operating income or loss? 4. The company is considering paying the Bradbury store manager an incentive commission of $3 per shirt (in addition to the salesperson's commissions).
