Problem 16-58 Sales and Variable Cost Variances; Current to Prior Year; Review of Chapter 14 (LO 16-4) RJM Enterprises is a manufacturer of consumer electronics products. The industry is very competitive, and RJM has seen its profits fall in recent years, including an operating loss of $18,770 last year. RJM was able to turn that around this year by aggressively cutting costs. The summarized financial results for RJM are shown below: Current Year $940, 170 Prior Year $1,332,459 Gross sales: Less variable costs Direct materials Direct labor Total contribution margin Fixed cost Operating income 451,770 244,200 $244,200 33,509 $210,691 $ 800,700 494,529 37,230 56,000 (18,770) $ Jim Green, the management accountant at RJM, is analyzing the company's performance for this year in order to explain to management the specific aspects that drove the company to success. Some of the information Jim obtained follows: Sales units Price Direct materials cost per unit of material Direct materials required per unit Direct labor required per unit Wage rate ($/hour) Current Year 40,700 $ 23.10 $ 7.40 1.50 0.60 $ 10.00 Prior Year 47,100 $ 28.29 $ 8.50 2.00 0.75 $ 14.00 Assume that RJM, for efficiency and to reduce cost, maintains little or no direct materials or work-in-process inventory.
