Multiple Choice

Solve the problem.
-The function $P(x) =-0.3 x^{2}+50 x-14$ describes a company's net monthly profit or loss and the function $\mathrm{C}(\mathrm{x}) =9 \mathrm{x}+14$ describes its monthly costs, where $\mathrm{x}$ represents the number of units produced. The total revenue function, $\mathrm{R}(\mathrm{x})$ , is such that $\mathrm{R}(\mathrm{x}) =\mathrm{C}(\mathrm{x}) +\mathrm{P}(\mathrm{x})$ . Find $\mathrm{R}(\mathrm{x})$ .

A) $\mathrm{R}(\mathrm{x}) =61 \mathrm{x}-0.3 \mathrm{x}^{2}$
B) $R(x) =59 x+0.3 x^{2}$
C) $R(x) =58 x-0.6 x^{2}$
D) $R(x) =59 x-0.3 x^{2}$
