A baker uses organic flour from a local farmer in all of his baked goods. For each batch of bread (x1), he uses 4 lbs. For a batch of cookies (x2), he uses 3 pounds, and for a batch of muffins (x3) he uses 2 pounds. The local farmer can supply him with no more than 24 pounds per week. The constraint that represents this condition is:
- x1 ≤ 8, x2 ≤ 8, x3 ≤ 8
- x1+ x2 + x3 ≥ 24
- x1 ≤ 6, x2 ≤ 8, x3 ≤ 12
- 4x1+ 3x2 + 2x3 ≤ 24
