Walmart purchases 10,000 packages of Tide laundry detergent weekly from Proctor & Gamble at $4.50 a package. To increase weekly sales of Tide, Walmart gives a 10% discount on each package sold. The original selling price for each package is $6.25. The allocated expenses are $2,000 and the allocated fixed costs are $3,500. The allocated total assets are $50,000. Calculate the profit, unit gross margin gross margin percentage, and return on investment (ROI). Assume Walmart sells all 10,000 packages. Calculate revenue: $53,600 $56,300 $56,800 $53,800
