5. Consider the cost function, C(x) = 25000 + 100x + 0.1x^2 where C is given in dollars. The average cost is given by c(x) = C(x)/x. a. Find the cost, average cost, and marginal cost at a production level of 100 units. b. Find the production level that will minimize the average cost. c. Find the minimum average cost.

(a) If $C ( x )$ is the cost of producing $x$ units of a commodity, then the average cost per unit is $c ( x ) = C ( x ) / x$ . Show that if the average cost is a minimum, then the marginal cost equals the average cost. (b) If $C ( x ) = 16,000 + 200 x + 4 x ^ { 3 / 2 } ,$ in dollars, find $( \mathrm { i } )$ the cost, average cost, and marginal cost at a production level of 1000 units; (ii) the production level that will minimize the average cost; and (iii) the minimum aver- age cost.
