-Business people are concerned with cost functions, revenue functions, and profit functions. Suppose the revenue $R ( x )$ for $x$ units of a product can be described by $R ( x ) = 410 x$ , and the cost $C ( x )$ can be described by $C ( x )$ $= 2900 + 110 x$ . Find the profit $P ( x )$ for $x$ units.

A) $P ( x ) = \frac { 300 } { x } - 2900$
B) $\mathrm { P } ( \mathrm { x } ) = 300 \mathrm { x } + 2900$
C) $P ( x ) = 300 x - 2900$
D) $P ( x ) = 520 x - 2900$
