Question

The cost C of producing x thousand calculators is given by the equation below. C = -1 4.4x^2 + 14,390x + 580,000 (x <150) The average cost per calculator is the total cost C divided by the number of calculators produced. Write a rational expression that gives the average cost per calculator when x thousand are produced The rational expression for the average cost is (Do not simplify.)

Answer 1

The average cost is the total cost (C) divided by the number produced (x), But "x" is actually in thousands.

Average Cost = C/(1000x)

But C = -14.4x² + 14,390x + 580000 so

Average Cost = (-14.4x² + 14,390x + 580000)/(1000x)
