I am having an issue finding the maximum operating income and I can't seem to figure it out.

Break-Even Sales Under Present and Proposed Conditions The division of costs between variable and fixed is as follows: $5,000,000 but will not affect the relationship between sales and variable costs. Required: 1. Determine the total variable costs and the total fixed costs for the current year. 1. Determine the total variable costs and the total fixed costs for the current year. Total vanable costs Total fixed costs 2. Determine (a) the unit variable cost and (b) the unit contribution margin for the current year. Unit variable cost Unit contribution margin 3. Compute the break-even sales (units) for the current year. units 4. Compute the break-even sales (units) under the proposed program for the following year. . units units 6. Determine the maximum operating income possible with the expanded plant. 7. If the proposal is accepted and sales remain at the current level, what will the operating income or loss be for the following year? 8. Based on the data given, would you recommend accepting the proposal? a. In favor of the proposal because of the reduction in break-even point. b. In favor of the proposal because of the possibility of increasing income from operations. c. In favor of the proposal because of the increase in break-even point. d. Reject the proposal because if future sales remain at the current level, the income from operations will increase
