c. W M16-15. Preparing Cost-Volume-Profit and Profit-Volume Graphs Manu's Tacos sells seven different burritos at a fixed price of $9. Assume variable costs are $6 per burrito and fixed operating costs are $120,000 per year. Required a. Determine the annual break-even point in tacos. b. Prepare a cost-volume-profit graph for the company. Use a format that emphasizes the contribution margin. The vertical axis should vary between $0 and $800,000 in increments of $100,000. The horizontal axis should vary between 0 tacos and 80,000 tacos, in increments of 10,000 tacos. Label the graph in thousands. c. Prepare a profit-volume graph for the company. The vertical axis should vary between $(150,000) and $150,000 in increments of $50,000. The horizontal axis should vary as described in requirement (b). Label the graph in thousands. d. Evaluate the profit-volume graph. In what ways is it superior and in what ways is it inferior to the traditional cost-volume-profit graph
