(a) Write the function for the model giving revenue in dollars, where x is the average price in dollars. R(x) = dollars (b) If each movie costs the store $10.00, write the function for the model that gives profit in dollars, where x is the average price in dollars. P(x) = dollars (c) Complete the table. (Round your answers to three decimal places.) Rates of Change of Revenue and Profit Rate of change Rate of change of revenue of profit Price (dollars per dollar) (dollars per dollar) $13 $14 $20 $21 $22 (d) What does the table indicate about the rate of change in revenue and the rate of change in profit at the same price? There is a range of prices beginning near $14 for which the rate of change of revenue is --Select-- (revenue is --Select-- )while the rate of change of profit is --Select- (profit is -Select- )
