2. A company called Gampa produces phone cases. Their marginal revenue and marginal cost (in 35) are expressed as a function of the number of phone cases 9- (in millions of cases) in the graph below. 2 4 6 8 10 12 14 q (a) (4 points) At what value of q are the prots 7r(q) increasing the fastest? What is the rate of increase of 7r(q) at this value of q? No justication is required. Don't forget the units! The prots will be increasing the fastest at q :l: , and the rate of increase (b) (8 points) Suppose that Gampa has a xed initial cost of 1 million $. How many phone cases should Gampa produce in order to maximize their prots? How much will their prots be then? Explain your reasoning in the box below
