If C(x) is the cost of producing x units of a commodity, then the average cost per unit is a(x) = C(x)/x. Consider the C(x) given below. Round your answers to the nearest cent.

C(x) = 54,000 + 90x + 4x3/2

(a) Find the total cost at a production level of 1000 units.
.......................................$

(b) Find the average cost at a production level of 1000 units.
................................dollars per unit

(c) Find the marginal cost at a production level of 1000 units.
........................... dollars per unit

(d) Find the production level that will minimize the average cost.
............................... units

(e) What is the minimum average cost?
