You have decided to buy an ice-cream cart to sell frozen desserts on weekends. The desserts will cost you $3.00 each and you plan to sell them for $5.00 each. The cart will cost you $10,000 and you expect to sell 300 desserts every weekend for the next one year. Assume that you buy the cart today and that you operate the cart for 1 year (52 weekends), what is the NPV of your investment at a discount rate of 4% APR?
