The marginal return to the first machine was 5,000 packages, the marginal return to the second machine was 4,000 packages (9,000 - 5,000)and the marginal return to the third machine was 3,000 packages (12,000 - 9,000). Thus, the marginal return to the third machine has to be less than 3,000 packages, which makes the total less than 15,000 packages.
