The daily production cost, C, of a special edition toy car is given by the function C(t)= 0.2t^2 - 10t + 650, where C(t) is in dollars and t is the number of cars made.

 

A. How many cars must be made to minimize the production cost?

 

B. Using the number of cars from part a), determine the cost

C(t)= 0.2t^2 - 10t + 650      if graphed, this is a bowl shaped parabola

    the minimum will occur at   t = - b/2a = - (-10)/(2* .2) = 10/ .4 = 25  cars

 

Cost of 25 cars will be  :      C (t) = 0.2 (252) - 10 (25) + 650 = ___________                   you can do the calcs..... cheeky
