Here, you do the same as the previous one, keeping in mind that X cuts TW in a 2:1 ratio.

What are the constraints?
When you graph the constraints the four points you can use are (0,0), (10,0), (0,2), and (6,2).
(10,0) is the point that gives you the maximum value which is 40.
2 1/2 = 2 8/16
so
2 8/16 + 1 1/16 = 3 9/16
The answer is the third option
5*2400=$12,000 is the total costs for 5 decks costing $2,400 each.
