Exercise 3.10

Cost Behavior

SmokeCity, Inc., manufactures barbeque smokers. Based on past experience,
SmokeCity has found that its total annual overhead costs can be represented by
the following formula: Overhead cost = \$543,000 + \$1.34X, where X equals number
of smokers. Last year, SmokeCity produced 20,000 smokers. Actual overhead costs
for the year were as expected.

Required:

1. What is the driver for the overhead activity?

_________________

For questions 2-4, Enter the final answers rounded to the nearest
dollar.

2. What is the total overhead cost incurred by SmokeCity last
year?

3. What is the total fixed overhead cost incurred by SmokeCity
last year?

4. What is the total variable overhead cost incurred by SmokeCity
last year?

those rounded figures in subsequent computations, if necessary.

5. What is the overhead cost per unit produced?

8. Recalculate Requirements 5, 6, and 7 for the following levels
of production: (a) 19,500 units and (b) 21,600 units.

Exercise 3.19

High-Low Method, Cost Formulas

The controller of the South Charleston plant of Ravinia, Inc.,
monitored activities associated with materials handling costs. The high and low
levels of resource usage occurred in September and March for three different
resources associated with materials handling. The number of moves is the
driver.

The total costs of the three resources and the activity output, as
measured by moves for the two different levels, are presented as follows:

 Forklift depreciation: Number of Moves Total Cost Low 6,500 \$1,800 High 20,000 \$1,800 Indirect labor Number of Moves Total Cost Low 6,500 \$74,250 High 20,000 \$1,35,000 Fuel and oil for forklift: Number of Moves Total Cost Low 6,500 \$4,940 High 20,000 \$15,200

Required:

“0” if required.

1. Determine the cost behaviour formula of each resource. Use the
high-low method to assess the fixed and variable components.

2. Using your knowledge of cost behavior, predict the cost of each
item for an activity output level of 9,000 moves. For interim computations,
carry amounts out to two decimal places. Round your final answer to the nearest
dollar.

3. Construct a cost formula that can be used to predict the total
cost of the three resources combined. If required, round your answers to two decimal
places.

Materials handling cost = \$ _________________ + \$
_________________ X

Using this formula, predict the total materials handling cost if
activity output is 9,000 moves.

Exercise 16.16

CVP: Before- and After-Tax Targeted Income

Head-Gear Company produces helmets for bicycle racing. Currently,
Head-Gear charges a price of \$230 per helmet. Variable costs are \$80.50 per
helmet, and fixed costs are \$1,255,800. The tax rate is 25 percent. Last year,
14,000 helmets were sold.

Required:

1. What is Head-Gear’s net income for last year?

\$ _________________

round the contribution margin ratio to two decimal places.

\$ _________________

3. Suppose Head-Gear wants to earn before-tax operating income of
\$900,000. How many units must be sold? Round to the nearest whole unit.

4. Suppose Head-Gear wants to earn after-tax net income of
\$650,000. How many units must be sold? Round to the nearest whole unit.

5. Suppose the income tax rate rises to 35 percent. How many units
must be sold for Head-Gear to earn after-tax income of \$650,000? Round to the
nearest whole unit.

Exercise 16.20

Contribution Margin, CVP, Net Income, Margin of Safety

Nail Glow, Inc., produces novelty nail polishes. Each bottle sells
for \$5.90. Variable unit costs are as follows:

Fixed overhead costs are \$34,475 per year. Fixed selling and
administrative costs are \$6,720 per year. Nail Glow sold 35,000 bottles last
year.

Required:

1. What is the contribution margin per unit for a bottle of nail
polish?

4. What was the margin of safety in revenue?

5. Suppose that Nail Glow, Inc., raises the price to \$6.50 per
bottle, but anticipated sales will drop to 28,750 bottles. What will the new
break-even point in units be? Round your answer up to the nearest whole number
of units.
