A store has determined that the number of Blu-ray movies sold monthly is approximately n(x) = 6750(0.928*) movies where x is the average price in dollars. (a) Write the function for the model giving revenue in dollars, where x is the average price in dollars. R(x) = (6750(.928)*)* (b) If each movie costs the store $10.00, write the function for the model that gives profit in dollars, where x is the aver P(x)=6750 (0.928)*x-67500(0.928)* Price (c) Complete the table. (Round your answers to three decimal places.) Rates of Change of Revenue and Profit Rate of change of revenue (dollars per dollar) 73.846 x $13 $14 $20 dollars $21 $22 -108.603 x x -799.272 x -748.153 dollars -839.151 x Rate of change of profit (dollars per dollar) 1982.591 x 1662.731 383.163 250.589 135.120 x x x
