"App Masters" has determined that the demand for the quantity of downloads of its new app priced at x dollars is given by D (x) = 50e-0.12x. d. Find the Elasticity of demand equation. e. At what price will App Masters maximize revenue? Round to the nearest cent. f. At x = $3, will a small increase in price cause total revenue to increase or decrease? Why? g. Suppose that market conditions dictate that the app must be priced on the interval [$2, $10]. What is the absolute maximum of the quantity demanded on this price interval
