Solve the problem.The MetroCity tractor company is planning to produce a new tractor. For the first year, the fixed costs for setting up production are $400,000. The variable costs for producing each tractor are $15,000. The revenue for each tractor is $32,000. Find the total cost C(x) of producing x tractors.
A. C(x) = 15,000x B. C(x) = 400,000x + 15,000x C. C(x) = 32,000x + 400,000 D. C(x) = 400,000 + 15,000x
