A manufacturer has a total cost function \( C(x) = 45000 + 100x + x^3 \) (in dollars) and a revenue function \( R(x) = 7903x \) (in dollars), where \( x \) is the production level (or number of items).

**A.** Find and simplify the profit function, \( P(x) \).

\[ P(x) = -x^3 + 7803x - 45000 \]

**B.** Find the derivative of the profit function (i.e., the Marginal Profit function).

\[ P'(x) = -3x^2 + 7803 \]

**C.** What level of production will maximize profit?

\[ x = 51 \] (Round to the nearest whole number if needed.)

**D.** What is the maximum profit?

Maximum Profit: \[ \$ \] (Round to the nearest dollar if needed.)
