Equillion, Inc., and Storis, Inc., are two companies in the pharmaceutical industry. Equillion has relatively high fixed costs related to research and development.

The amount paid is a percent of sales. Thus, Storis has relatively high variable costs and relatively low fixed costs: Which company has the higher operating leverage?
