Ivanhoe Willis is the advertising manager for Bargain Shoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $24,940 in fixed costs to the $232,200 currently spent. In addition, Ivanhoe is proposing that a 5% price decrease ( $40 to $38 ) will produce a 25% increase in sales volume (17,200 to 21,500 ). Variable costs will remain at $25 per pair of shoes. Management is impressed with Ivanhoe's ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety.
