Current Designs manufactures two different types of kayaks, rotomolded kayaks and composite kayaks. The following information is available for each product line. The company's fixed costs are $836,200. An analysis of the sales mix identifies that rotomolded kayaks make up 80% of the total units sold. Assume that the sales mix changes, and rotomolded kayaks now make up 70% of total units sold. Calculate the total number of units that would need to be sold to earn a net income of $2,036,580 and identify how many units of each type of kayak will be sold at this level of income. Required sales units Assume that Current Designs will have sales of $3,000,000 with two-thirds of the sales dollars in rotomolded kayaks and onethird of the sales dollars in composite kayaks. Assuming $673,000 of fixed costs are allocated to the rotomolded kayaks and $163,200 to the composite kayaks, prepare a CVP income statement for each product line. Calculate the degree of operating leverage for each product line, (Round answers to 2 decimal places, e.g. 52.75.)
