How do I solve this?

Let C(x) be the cost (in dollars) of manufacturing x bicycles per day in a certain factory. Interpret C(70) = 5000 and C'(70) = 65. What does C(70) = 5000 represent in the context of this problem? A. The marginal cost of producing 70 bicycles is $5000. O B. The cost of producing the 71st bicycle is $5000. O C. The cost of producing 70 bicycles is $5000. What does C'(70) = 65 represent in the context of this problem? O A. The cost of producing 70 bicycles is $65. O B. The approximate cost of producing any one bicycle is $65. O C. The approximate cost of producing the 71st bicycle is $65
