Table 4.2 shows cost, $C(q),$ and revenue, $R(q)$
(a) At approximately what production level, $q$, is profit maximized? Explain your reasoning.
(b) What is the price of the product?
(c) What are the fixed costs?
$$\begin{array}{l|r|r|r|r|r|r|r}\hline q & 0 & 500 & 1000 & 1500 & 2000 & 2500 & 3000 \\\hline R(q) & 0 & 1500 & 3000 & 4500 & 6000 & 7500 & 9000 \\\hline C(q) & 3000 & 3800 & 4200 & 4500 & 4800 & 5500 & 7400 \\\hline\end{array}$$
