Chapter 13: Joint Management of Revenues and Costs 13-19
Exercises
1. Deluxe Doll Manufacturing produces several different types of dolls. Product demand escalates
during the holiday season in December. In the past, the company filled customer orders by
anticipating demand increases and then manufacturing inventories in advance.
Recently, competition from other toymakers has escalated. Deluxe needs to reduce prices and,
therefore, cut costs. The current cost for Deluxe’s best seller, Bouncy Baby Doll, is $12. To be
competitive, the marketing manager believes that the price should be 10% lower than the current
price. The company currently achieves a pretax return of 10% on sales of the dolls, and the top
managers want to continue this rate of return.
Following are the per-unit costs for baby dolls, based on production of 500,000 per year:
Direct materials (variable) $ 4.50
Direct labor (variable) 1.00
Machining costs (fixed depreciation and maintenance) 5.00
Inspection costs (variable) 0.50
Marketing costs (fixed) 0.25
Administrative costs (fixed) 0.75
Total cost $12.00
a. Calculate the price recommended by the marketing department.
b. Given the price you calculated in Part (a), calculate the new contribution margin and the target
cost.
c. Calculate the target cost reduction for each cost category, assuming proportional cost reduction
across categories.
2. SRB Corporation manufactures and sells espresso machines for $80 each. In a recent accounting
period, SRB incurred the following costs to produce 5,000 espresso machines:
Direct material $ 18,250
Direct labor 36,250
Variable manufacturing overhead 22,250
Fixed manufacturing overhead 19,000
Variable nonmanufacturing costs 19,750
Fixed nonmanufacturing costs 21,000
Total $136,500
Assume that SRB plans to increase the price of its current espresso machines by 30% next year, with
a resultant 40% drop in unit sales. Use the appropriate natural logarithms below to calculate the
indicated amounts.
ln (0.1) = -2.303 ln (0.6) = -0.511 ln (1.1) = 0.095
ln (0.3) = -1.204 ln (0.7) = -0.357 ln (1.3) = 0.262
a. Price elasticity of demand
b. Profit maximizing price
c. Total cost per unit to achieve a 30% profit margin
3. GYG Corporation manufactures and sells wine racks for $120 each. In a recent accounting period,
GYG incurred the following costs to produce 300 racks:
Direct material $ 4,095
Direct labor 5,175
Variable manufacturing overhead 4,335
Fixed manufacturing overhead 1,140
Variable nonmanufacturing costs 4,185
Fixed nonmanufacturing costs 1,260
Total $20,190
