Multiple Choice

Solve the problem.
-Steve invests in a circus production. The cost includes an overhead of $56,000, plus production costs of $5000 per performance. A sold-out performance brings in $13,000. Let x represent the number of sold-out
Performances and write the cost function, C and revenue function, R.

A) $C ( x ) = 56,000 + 5000 x$
$R ( x ) = 13,000 x$
B) $C ( x ) = 56,000 + 13,000 x$
$R ( x ) = 5000 x$
C) $C ( x ) = 5000 x$
$R ( x ) = 56,000 + 13,000 x$
D) $C ( x ) = 56,000 x + 5000$
$R ( x ) = 13,000 x$
