Question

The average cost when producing x items is found by dividing the cost function, C(x), by the number of items, x. When is the average cost less than 100, given the cost function is C(x) = 20x + 160?

Answer 1

Answer:

When the produced item greater than 2, the average cost will be less than 100

Step-by-step explanation:

C(x) / x = 100 ... when x items produced and the cost is 100

(20x + 160) / x = 100

20x + 160 = 100x

80x = 160

x=2
