A factory selling cell phones has a marginal cost function C(x) = 0.01x2-3x+229, where a represents the number of cell phones, and a marginal revenue function given by R(x) = 429 - 2x. Find the area between the graphs of these curves and x = 0. What does this area represent? Ototal revenue for 200 cell phones sold Ototal profit for more than 200 cell phones sold Ototal profit for 200 cell phones sold O total cost for 200 cell phones sold
