Solve the Problem $C ( x ) = 30 x + 20,000$

Solve the problem.
-A company that produces computer printers has costs given by the function $C ( x ) = 30 x + 20,000$ , where $x$ is the number of computer printers manufactured and $C ( x )$ is measured in dollars. The average cost to manufacture each computer printer is given by
$$\bar { C } ( x ) = \frac { 30 x + 20,000 } { x }$$
Find $\bar { C } ( 250 )$ . (Round to the nearest dollar, if necessary.)

A) $\$ 110$
B) $\$ 90$
C) $\$ 38$
D) $\$ 40$
