You are trying to figure out how many donuts you need to sell from your new food truck in order to break even. The monthly rent for the food truck is 2,000 dollars and you also need to pay a monthly licensing fee of 100 dollars and estimate that your cost of operating the truck (gas, etc.) is another 100 dollars. You plan to sell your donuts for 2 dollars and 50 cents each and the cost of ingredients is 50 cents per donut. Based on these numbers, how many donuts do you need to sell in a month to break even?
