PROBLEM 3-30 Graphing; Incremental Analysis; Operating Leverage [LO3-2, LO3-4, LO3-5, Angie Silva has recently opened The Sandal Shop in Brisbane, Australia, a store that specializes LO3-6, LO3-8] in fashionable sandals. Angie has just received a degree in business and she is anxious to apply the principles she has learned to her business. In time, she hopes to open a chain of sandal shops. As a first step, she has prepared the following analysis for her new store: 1. How many pairs of sandals must be sold each year to break even?

It will cost her an additional $8,000 per year to convert the part-time position to a full-time position. Angie believes that the change would bring in an additional $25,000 in sales each year.

During the first year, the store sold only 3,000 pairs of sandals and reported the following operating results: a. What is the store's degree of operating leverage? b. Angie is confident that with a more intense sales effort and with a more creative advertising program she can increase sales by 50% next year. What would be the expected percentage increase in net operating income? Use the degree of operating leverage to compute your
