I need help with these. I hope the explanation is simple

In the month of June, Mandeep's Beauty Salon gave 3,100 haircuts, shampoos and permanents at an average price of $30. During the month, fixed costs were $20,900 and variable costs were 75% of sales. Determine the contribution margin in dollars, per unit, and as a ratio. (Round contribution margin per unit to 2 decimal places, e.g. 5.27.) Contribution margin (in dollars) $ Contribution margin (per unit) Question 1 $ Contribution margin (ratio) Find the missing figures for each of the independent cases shown below. (Hint: reconstruct income statement for each scenario) Selling price/unit Variable costs/unit Units sold Contribution margin (total) 160,000 Profit (loss) Fixed costs 100,000 80 10,000 15 10 25,000 0 8 6 (1,000) Question 2 4,500 8,000 80 500 12,000 10 1,000 6,500 (1,500) * (Round this answer to two decimal places) Currently, the selling price per unit of product X is $340. The variable cost per unit is $280 and the total fixed costs are $630,000. If the company required a net profit of $36,000, how many units would need to be sold? Calculate the following: (Round answers to o decimal places, e.g. 5,275.) The contribution margin per unit S The number of units to be sold to break even The total sales achieved at break-even $ Question 3 The break-even in units required to make $36,000 net profit Using the above information, a proposal is being evaluated to increase the unit selling price to $360. Calculate the following: (Round answers to 0 decimal places, e.g. 5,275.) The number of units to be sold to break even based on the new selling price The total sales achieved at the new selling price to break even $
