The function C(x)=20x+4,000 represents the cost to produce x number of items. How many items should be produced so that the average cost is less than $40?

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
