Performance Company sells two types of performance tires. The lower-priced model is guaranteed for only 50,000 miles; the higher-priced model is guaranteed for 150,000 miles.

If the sales mix shifts so that the company begins to sell more units of the lower-priced tire, explain how the company’s break-even point in units will change.
