When the price is $2.00 each, 6000 fruit bars will be sold. If the price of a fruit bar is raised to $4.00, sales will drop to 5500. a) The cost for the bars is given by the function C(x) = 30 + 0.25x. Determine the marginal cost of purchasing 3000 bars. b) Determine the marginal profit from the sale of 3000 bars.For the distance time graph given, sketch the velocity and acceleration 8 points functions.
