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