#10. Marco is considering leaving his current job, which pays $75,000 per year, to start a new company that develops applications for smart phones. Based on market research, he can sell about 50,000 units during the first year at a price of $4 per unit. With annual overhead costs and operating expenses amounting to $145,000, Marco expects a profit margin of 20 percent. This margin is 5 percent larger than that of his largest competitor, Apps, Inc. If Marco decides to embark on his new venture, what will his accounting costs be during the first year of operation? His implicit costs? His opportunity costs? Suppose that Marco's estimated selling price is lower than originally projected during the first year. How much revenue would he need in order to earn accounting and economic profits? Show all work. Do you think Marco should leave his job?
