$600k on leasing the spots? around $1700 per day on lease, $800 per day as employee and other expenses without considering any profit and smooth running of business. Let's assume he makes 100% profit from the hot dogs. Then he should sell 5000 hotdogs per day minimum i.e. 1.8 million hotdogs per year. If there are 5 million visitors, atleast 35% visitors should stopby there.
