-A sports trainer has monthly costs of $50.51 for phone service and $43.53 for his website and advertising. In addition he pays a $10 fee to the gym for each session in which he trains a client. His
Monthly costs can be represented by the function $C ( x ) = 94.04 + 10 x$ where x is the number of training sessions. Write a function representing the average cost $\bar { C } ( x )$ for x Sessions.

A) $\bar { C } ( x ) = \frac { 94.04 + 10 x } { x }$
B) $\bar { C } ( x ) = 94.04 + 10 x ^ { 2 }$
C) $\bar { C } ( x ) = \frac { 94.04 } { x } + 10 x$
D) $\bar { C } ( x ) = 94.04 x + 10 x ^ { 2 }$
