3. A political candidate wants to use a combination of radio and TV ads in her campaign. Her aides have found that each minute on TV reaches 11 million viewers while each 1- minute radio spot is estimated to reach 1 million listeners. The campaign hopes to reach at least 400 million people via radio and TV combined and will purchase at least 100 minutes combined total for all radio and TV ads and also wants to minimize total advertising costs. Suppose that TV ads are $5 million/minute and radio ads are $3 million/minute Let x = number of minutes of TV ads purchased let y = number of minutes of radio ads purchased. a) Write all constraints for this linear programming problem X 7/ 0, 4 71 0 * 5 x + By >, 400 x + y 7 / 100min b) What is the overall goal in solving this particular linear programming problem? Write a complete sentence. the goal to solving this question Is to see how many mins will it take for 5million c) What is the objective function? people for tu Ade and 3 million people for Radio Malmer 5 x + 3 y = P (people) d) Graph the region of feasible solutions for the constraints determined above. Shade the region of feasible solutions. Label coordinates of all intersections and intercepts in the graph
