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) = 8x - 1/9x + 2. Find the average cost for each of the following production levels. 30 units x units Find the marginal average cost function. The average cost for 30 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 \'(x) = .

Solution

a)(8- 1/30)/(272) *100 =2.93$ b)(8- 1/x)/(9x+2) c)(((9x+2)*1/x^2)-9(8- 1/x))/(9x+2)^2 =(2/x^2 +18/x -72)/(9x+2)^2
