I have uploaded file to solve the problem of limit numerically, limit Algebraically, and polynomial function with degree. 

Also this question, "You start a Cake business to earn money for college. The fixed cost of this business is a$ and the variable cost is b$ per cake. You will sell each cake for $c."

After you finish, please send me a copy of Desmos for each questions and one Word file that shows all the answers of these questions.

Thank you for helping me.
