A company manufacturers and sells $x$ electric drills per month. The monthly cost and price-demand equations are \begin{align*} C(x) &= 63000 + 60 x,\\ p &= 180 - \frac{x}{30}, \qquad 0 \leq x\leq 5000. \end{align*} (A) Find the production level that results in the maximum revenue.
Production Level =
