I have good news... I need help analyzing one of our current products, the Air-Accountant shoes. Here is the information about the product: Selling Price $44 (accountants are cheap) DM$16DL$10VarOh$5 Fixed costs per year - $80,000 Currently, we are selling 6,800 pairs of Air-Accowtants per year: We need to determine the following: 1. Break-even units and sales dollars 2. Margin of safety in units, sales dollars, and percentage 3. Operating Leverage 4. What happens if we switch material suppliers? We would pay an extra $1.50 per pair in materials but the higher quality could lead to a 10% increase in sales (units). Should we do this? 5. Going back to the original data, what if we spent $5,000 on advertising this year and it increased sales (units)by 4%. should we go forward with this plan? 6. What is the minimum percentage sales would have to increase for the $,000 of advertising to make sense
