The total cost $C(q)$ of producing $q$ goods is given by: $$C(q) = 0.01q^{3}-0.6q^{2}+14q$$

What is the fixed cost?
fixed cost = dollars

What is the maximum profit if each item is sold for 6 dollars? (Assume you sell everything you produce. Also note that you can only produce a whole number of goods.)
maximum profit = dollars

Suppose we fix production at 32 goods produced, and that they all sell when the price is 6 dollars each. Also suppose that for each 1 dollar increase in price, 2 fewer goods are sold (so if the price is 7 dollars, 30 of the 32 goods being produced are sold.)

To maximize profit in this case, we should ? decrease increase neither increase nor decrease the price by dollars.
(Enter zero if the price should remain at 6 dollars.)
