Betty Willis is the advertising marager 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 $23.600 in food costs to the $129.000 currently spent. In addition, Betty is proposing that a 5% price decrease ( $20 to $19 ) will produce a 208 increase in sales volume (20,000 to 24,000). Variable costs will remain at $12 per pair of shoes. Management is impressed with Betty/s ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety.
