You are trying to figure out how many cupcakes you need to sell from your new food truck in order to break even. The monthly rent for the food truck is 1,500 dollars and you also need to pay a monthly licensing fee of 150 dollars and estimate that your cost of operating the truck (gas, etc.) is another 150 dollars. You plan to sell your cupcakes for 3 dollars each and the cost of ingredients is 70 cents per cupcake. Based on these numbers, how many cupcakes do you need to sell in a month to break even? Please show or explain your calculation and provide your result.
