2 CHAPTER 1. MATHEMATICAL MODELING BY EXAMPLE Constraints: •producing x1 toy soldiers and x2 toy trains requires (a) 1x1 +1x2 hours in the carpentry shop; there are 80 hours available (b) 2x 1 +1x2 hours in the finishing shop; there are 100 hours available •the number x1 of toy soldiers produced should be at most 40 Variable domains: the numbers x 1, x2 of toy …
