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) Use an online Simplex calculator to find the optimal number minutes of TV and radio ads the candidate should purchase. Attach a screen shot of the result of the simplex calculator. (b) Write a sentence answer stating the optimal number of minutes the candidate should purchase of both TV and radio ads. What is the minimum cost the candidate can achieve with the given constraints
