David is determined to make $50,000 after tax. After listening to your advice, he makes a radical choice: discontinuing the production of Bock and Stout beers

Given David’s current productive capacity, can he now achieve his goal? 

How many cases of Ale and Pilsner would he have to sell to reach his goal? 

Given the 2:1 sales mix and the available number of machine hours, what is the maximum after-tax profit David could attain using this strategy?
