Atlantic Company produces a single product. For the most  recent year, the company’s net operating income computed by the absorption costing method was $7,800, and its net operating income computed by the variable costing method was $10,500. The company’s unit product cost was $15 under variable costing and $24 under absorption costing.  If the ending inventory consisted of 1,460 units, how many units must have been in the beginning inventory.

Black Company uses the weighted-average method in its process costing system. The company’s ending work-inprocess inventory consists of 6,000 units, 75 percent complete with respect to materials and 50 percent complete with respect to labor and overhead. If the total  dollar value of the inventory is $80,000 and the cost per equivalent unit for labor and overhead is $6.00, what is the cost per equivalent unit for materials?
Total Value = Equivalent units for Material* cost per equivalent unit for materials + Equivalent units for Labor* cost per equivalent unit for Labor & OH

At Overland Company, maintenance cost is exclusively a variable cost that varies directly with machine-hours. The performance report for July showed that actual maintenance costs totaled $11,315 and that the associated rate variance was $146 unfavorable. If 7,300 machine-hours were actually worked during July, what is the budgeted maintenance cost per machine-hour?

Denny Corporation is considering replacing a technologically  obsolete machine with a new state-of-the-art  numerically controlled machine. The new machine would cost $600,000 and would have a 10-year useful life. Unfortunately, the new machine would have no salvage value. The new machine would cost $20,000 per year to  operate and maintain, but would save $125,000 per year in labor and other costs. The old machine can be sold now for scrap for $50,000. What percentage is the simple rate of return on the new machine rounded to the nearest tenth of a percent? (Ignore income taxes in this problem.)
