These 3 sections A, B & C go together and I am in need of help. I don't know what I am not understanding.

The total fixed costs for the company are $109,000. Required: o. What is the anticipated level of profits for the expected sales volumes? b. Assuming that the product mix would be 45 percent chicken and 55 percent fish at the break-even point, compute the break-even volume using weighted-average contribution margin. c. If the product sales mix were to change to four chicken tacos for each fish taco, what would be the new break-even volume? Complete this question by entering your answers in the tabs below. What is the anticipated level of profits for the expected sales volumes? Assuming that the product mix would be 45 percent chicken and 55 percent fish at the break-even point, compute the breakeven volume using weighted-average contribution margin. (In your computations, round up the total units to break-even to the nearest whole number and round other intermediate calculations to 2 decimal places. Round your final answers up to the nearest whole unit.) If the product sales mix were to change to four chicken tacos for each fish taco, what would be the new break-even volume? (In your computations, round up the total units to break-even to the nearest whole number and round other intermediate calculations to 2 decimal places. Round your final ansvers up to the nearest whole unit.)
