Compute the slope (change in cost divided by change in people). For example,
(22.50 − 9) / (5 − 2) = 13.50 / 3 = 4.50.
So the rate of change is $4.50 per person. The cost function is C(p) = 4.50 p (dollars).
(22.50 − 9) / (5 − 2) = 13.50 / 3 = 4.50.
So the rate of change is $4.50 per person. The cost function is C(p) = 4.50 p (dollars).
