A Food Truck can be a good study of scale. Every sale should make some money and the scale can determined by fixed costs divided by the net profits per sale - if your equipment lease costs $30 per day, and you sell a burger for a net $1, you must sell 30 burgers per day. If you maximize profit margins, vertically integrate as much as possible ( hello family labor ) and really dig in to your customer base to find a great fit that they are willing to pay good margins for, then you don't have to sell a million burgers from a hundred trucks to take a weekend off.
