Jim's Camera shop sells two high-end cameras, the Sky Eagle and Horizon. The demands and selling prices for these two cameras are as follows. DS = demand for the Sky Eagle PS = selling price of the Sky Eagle DH = demand for the Horizon PH = selling price of the Horizon DS = 226 0.60PS + 0.35PH DH = 280 + O.IOPS 0.64PH The store wishes to determine the selling price that maximizes revenue for these two products. Develop the revenue function R (in terms of PS and PH only) for these two models, and find the revenue maximizing prices (in dollars). (Round your answers to two decimal places.) Revenue R = Price for Sky Eagle PS = S Price for Horizon PH = S Optimal revenue R = S
