Solved by verified expert: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.

2. 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.
Let x be the number of cakes sold.
a) Formulate a cost function C(x).
b) Formulate a revenue function R(x).
c) Generate a profit function P(x).
d) Find the break-even point. (how many cakes?)
e) How many cakes do you need to sell to generate a profit of $2,500?
f) Find the average profit function Avg P(x).
g) Find the derivative of Avg P(x).
h) Find the rate of change when 200 cakes are produced and sold (average profit function).
