Problem 7-58 Multiple Products, Break-Even Analysis, Operating Leverage Carlyle Lighting Products produces two different types of lamps: a floor lamp and a desk lamp.

Floor lamps sell for $30, and desk lamps sell for $20. The projected income statement for the coming year follows:

Sales $600,000 Total variable cost 400,000 Contribution margin $200,000 Total fixed cost 150,000 Operating income $ 50,000 The owner of Carlyle estimates that 60% of the sales revenues will be produced by floor lamps and the remaining 40% by desk lamps. Floor lamps are also responsible for 60% of the variable cost. Of the fixed cost, one-third is common to both products, and one-half is directly traceable to the floor lamp product line.

Required:
1. Compute the sales revenue that must be earned for Carlyle to break even. (Round the contribution margin ratio to six digits and sales revenue to the nearest dollar.)
2. Compute the number of floor lamps and desk lamps that must be sold for Carlyle to break even. (Round the contribution margin per unit and variable cost per units to three significant digits.)
3. Compute the degree of operating leverage for Carlyle. Now assume that the actual revenues will be 40% higher than the projected revenues. By what percentage will profits increase with this change in sales volume?
