Solve Problems Using Systems of Linear Equations
-Steve invests in a circus production. The cost includes an overhead of $\$ 36,000$ , plus production costs of $\$ 5000$ per performance. A sold-out performance brings in $\$ 8000$ . Let $x$ represent the number of sold-out performances and write the cost function, $C$ and revenue function, $R$ .

A) $C ( x ) = 36,000 + 5000 x$
$R ( x ) = 8000 x$
B) $C ( x ) = 36,000 + 8000 x$
$R ( x ) = 5000 x$
C) $C ( x ) = 5000 x$
$R ( x ) = 36,000 + 8000 x$
D) $C ( x ) = 36,000 x + 5000$
$R ( x ) = 8000 x$
