The total cost in hundreds of dollars to produce x units of
     The total cost (in hundreds of dollars) to produce x units of a product is C(x) =6x-5/8x+1. Find the average cost for each of the following production levels. 20 units x units Find the marginal average cost function. The average cost for 20 units is  per unit. (Round to the nearest hundredth as needed.) The average cost for x units is  hundred dollars per unit. The marginal average cost function is  . 
  
  Solution
a.71.4 b.(6x-5)/(8x+1) c.dC/dx=6/(8x+1)-8(6x-5)/(8x-1)^2
