Multiple Choice

Solve the problem.
-The function $\mathrm{w}(\mathrm{x}) =5 \mathrm{x}-3$ describes a company's monthly costs in wages and $\mathrm{p}(\mathrm{x}) =2 \mathrm{x}-9$ describes the cost of production, where $x$ represents the number of units produced. Find the function $\mathrm{c}(\mathrm{x})$ that describes the total cost of producing $\mathrm{x}$ units.

A) $c(x) =3 x-12$
B) $c(x) =7 x+6$
C) $\mathrm{c}(\mathrm{x}) =7 \mathrm{x}-12$
D) $c(x) =3 x+6$
