I am searching for the correct answer to this general accounting problem with proper accounting rules.

Delta Tools Inc. sold 500,000 units of its product for 80 per unit in 2023. The variable cost per unit is 65, and total fixed costs are 2,000,000. Delta's manufacturing manager proposes upgrading to an automated system. If accepted, the proposal will: - Increase annual fixed costs to 6,000,000, and - Decrease variable costs to 60 per unit. Delta expects to maintain the same sales volume and selling price. What would be the new contribution margin per unit and the new operating profit if the proposal is accepted
