The Vice President for Sales and Marketing at Waterways Corporation is planning for production needs to meet sales demand in the coming year. He is also trying to determine how the companys profits might be increased in the coming year. This problem asks you to use cost-volume-profit concepts to help Waterways understand contribution margins of some of its products and decide whether to mass-produce any of them. Waterways markets a simple water control and timer that it mass-produces. Last year, the company sold 751,000 units at an average selling price of $4.90 per unit. The variable costs were $2,575,930, and the fixed costs were $772,779. (a1) What is the products contribution margin ratio? (Round ratio to 0 decimal places, e.g. 25%.) Contribution margin ratio Type your answer here % (a2) What is the companys break-even point in units and in dollars for this product? Break-even point in units units Break-even point in dollars $ (a3) What is the margin of safety, both in dollars and as a ratio? (Round ratio to 0 decimal places, e.g. 25%.) Margin of safety in dollars $ Margin of safety ratio % (a4) If management wanted to increase its income from this product by 10%, how many additional units would have to be sold to reach this income level? Waterways would have to sell an additional Type your answer here units (a5) If sales increase by 49,000 units and the cost behaviors do not change, how much will income increase on this product? Income will increase by $Type your answer here (b1) Waterways is thinking of mass-producing one of its special-order sprinklers. To do so would increase variable costs for all sprinklers by an average of $0.70 per unit. The company also estimates that this change could increase the overall number of sprinklers sold by 10%, and the average sales price would increase $0.20 per unit. Waterways currently sells 497,000 sprinkler units at an average selling price of $25.60. The manufacturing costs are $6,925,390 variable and $1,733,086 fixed. Selling and administrative costs are $2,617,010 variable and $783,290 fixed. If Waterways begins mass-producing its special-order sprinklers, how would this affect the company?
