Missing fixed costs prevent exact calculation Steps:

• Contribution per unit X: 120 - 110 = 10.
• Contribution from 25,000 units X: 25,000 × 10 = 250,000.
• Contribution per unit Y: 130 - 115 = 15.
• Total contribution needed = fixed costs + 80,000; required Y units = (fixed costs + 80,000 - 250,000) / 15. Not enough information: Fixed costs not provided, so cannot determine exact units of Y.

Final answer: Not enough information.
