Solve the problem.You invested $34,200 and started a business selling vases. Supplies cost $17 per vase and you are selling each vase for $36. Let x represent the number of vases produced and sold and write the cost function, C, and revenue function, R.
A. C(x) = 17x + 34,200x R(x) = 36x B. C(x) = 17x + 36 R(x) = 34,200x C. C(x) = 17x + 34,200 R(x) = 36 D. C(x) = 17x + 34,200 R(x) = 36x
