I have no idea where to start with this. I really could use some help. It would be great thanks. =)

The total cost C(q) of producing q goods is given by:

C(q)= .01q^3-.6q^2+13q

A) What is the maximum profit if each item is sold of $7 (assume you sell everything you produce.)

B) Suppose exactly 34 goods are produced. They all sell when the price is $7 each but for each $1 increase in price 2 fewer goods are sold. Should the price be raised, and if so by how much?
