I need help with the problem below. I tried several times to solve questions 6, 7 and 8, without success. Please help

Determine the amount of sales (units) that would be necessary under Break-Even Sales Under Present and Proposed Conditions Darby Company, operating at full capacity, sold 95,850 units at a price of $54 per unit during the current year. Its income statement for the current year is as follows: Sales $5,175,900 Cost of goods sold 2,556,000 Gross profit $2,619,900 Expenses: Selling expenses $1,278,000 Administrative expenses 1,278,000 Total expenses 2,556,000 Income from operations $63,900 The division of costs between fixed and variable is as follows: Variable Fixed Cost of goods sold 70% 30% Selling expenses 75% 25% Administrative 50% 50% expenses Management is considering a plant expansion program that will permit an increase of $432,000 in yearly sales. The expansion will increase fixed costs by $43,200, 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. Enter the final answers rounded to the nearest dollar. Total variable costs $ 3,386,700 Total fixed costs 1,725,300 2. Determine (a) the unit variable cost and (b) the unit contribution margin for the current year.
