What has to produce the company in order to maximize its weekly sales turnover?
we define 2 decisions variables
x1: number of thousands of 15 inches screens produced each week, x2: number of thousands of 17 inches screens produced each week.
The sales turnover (in thousands of dollars) associated a production (x1, x2) is z = 250x1 + 450x2
we should not exceed the outputs : x1 + (3/2) =21
