I included my work below. Not sure why my answer isn't correct. I subtracted the old profit from the new profit taking into account the decrease in sales.

Couzen's Company's cost structure is dominated by variable costs with a contribution margin ratio of 0.28 and fixed costs of $490,500. Every dollar of sales contributes 28 cents toward fixed costs and profit. The cost structure of a competitor, Jones \& Family, is dominated by fixed costs with a higher contribution margin ratio of 0.78 and fixed costs of $2,534,250. Every dollar of sales contributes 78 cents toward fixed costs and profit. Both companies have sales of $4,087,500 annually. Required: a. Compare the two companies' cost structures. b. Suppose that both companies experience a 12 percent decrease in sales volume. By how much would each company's profits decrease? Answer is complete but not entirely correct.
