Hello, can someone please show me how to solve this. I could not find an easy to follow example in my textbook. Thanks a ton!

Multiple-Product Break-even, Break-Even Sales Revenue Cherry Blossom Products Inc. produces and sells yoga-training products: how-to DVDs and a basic equipment set (blocks, strap, and small pillows). Last year, Cherry Blossom Products sold 13,500 DVDs and 4,500 equipment sets. Information on the two products is as follows: DVDs Equipment Sets Price $8 $25 Variable cost per unit 15 Total fixed cost is $89,780. Suppose that in the coming year, the company plans to produce an extra-thick yoga mat for sale to health clubs. The company estimates that 9,000 mats can be sold at a price of $20 and a variable cost per unit of $12. Total fixed cost must be increased by $29,920 (making total fixed cost $119,700). Assume that anticipated sales of the other products, as well as their prices and variable costs, remain the same. 1. What is the sales mix of DVDs, equipment sets, and yoga mats? 3:1:2 2. Compute the break-even quantity of each product. Break-even DVDs 3,375 X units Break-even equipment sets 450 X units Break-even yoga mats 1,125 X units 3a. Prepare an income statement for Cherry Blossom Products for the coming year. Cherry Blossom Products Inc. Income Statement For the Coming Year Sales $ 400,50 Total variable cost 119,70 Contribution margin Total fixed cost Operating income $ 55,080 3b. What is the overall contribution margin ratio? Use the contribution margin ratio to compute overall break-even sales revenue. (Note: Round the contribution margin ratio to the nearest whole percent; round the break-even sales revenue to the nearest dollar.) Overall contribution margin ratio | 42.69 X % Overall break-even sales revenue $ 280,394 x 4. Compute the margin of safety for the coming year in sales dollars. $ 339,750 x
