You make and sell x pizzas. In dollars, your income is R(x) = 10x-.03x^2 and your cost is
C(x) = 3 + 4x + 0.1x^2.

a) Describe the following as functions of x: The profit, the average profit per pizza, and the
marginal profit per pizza.

b) What is the demand function for your business? If the price of a pizza is p, how many
pizzas should you expect to sell?

c) How many pizzas should you make to maximize your prots? What will the price of a pizza
be?

Can anyone give me a step by step way to solve these?
