A market analyst finds that if a company produces and sells $x$ garlic presses annually, the total profit in dollars is $$P(x) = 6 x+ 0.3 x^2 - 0.0012 x^3 - 362$$ Graph the function $P$ in an appropriate viewing rectangle and use the graph to answer the following.

When just a few garlic presses are produced, the company loses money (i.e., profit is negative). For example $P(10) = -273.2$, so the company loses $273.20 if it produces and sells only 10 garlic presses. How many garlic presses must the company produce to break even?

Number of garlic presses =

---

Does the profit increase indefinitely as more garlic presses are produced and sold, or is there a largest possible profit the firm could earn? If there is a maximum profit, enter that value. If profit could increase indefinitely, enter None.

Maximum profit = $
