Question

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. Consider the cost function C(x) given below. (Round your answers to the nearest cent.)

C(x) = 16,000 + 240x + 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.
$  per unit

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

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

(e) What is the minimum average cost?
$  per unit

Explanation / Answer

C(x)=16000+240x+4x3/2

a.C(1000)=16000+240(1000)+4(1000)3/2 =$287622.8

c. Marginal cost,C'(1000)=240 +4(3/2)(1000)1/2=$429.7
