Find the derivative of the tunction at the given point and interpret the physical meaning of this quantity. Include units in your answer. 4) The cost C. in dollars. of a rental car driven for m miles is given by C(m) = 25 + 0.16 m. Find 0150). A) C'(50) = 8 dollars; the instantaneous cost is 8.00 when the car is driven 50 miles. B) C'(50) = 0.16 dollars; the cost increases at an instantaneous rate of $0.16 when the car is driven 50 miles. C) C'(50) = 0.16 dollars per mile; the cost increases at an instantaneous rate of $0.16 per mile when the car is driven 50 miles. D) C'(50) : 8 dollars pr mile; the cost increases at an instantaneous rate of:8.00 per mile when the car is driven 50 miles
