3. The contribution format income statement at the 5,000 unit level of activity.

Answer to Problem 7P

Solution:

1.

Expenses	Classification
Cost of goods sold	Variable
Advertising expenses	Fixed
Shipping expenses	Mixed
Salaries and commissions	Mixed
Insurance expense	Fixed
Depreciation expenses	Fixed

2. The total cost equation for shipping expenses is $Y=\text{ \$18,000 }+\text{ \$4*X}$.

The total cost equation for Salaries and Commissions is $Y=\text{ \$30,000 }+\text{ \$12*X}$.

Sales		$500,000
Variable expenses:
Cost of goods sold	$300,000
Shipping expenses	$20,000
Salaries and commissions	$60,000
Total variable expenses		$380,000
Contribution margin		$120,000
Fixed expenses:
Advertising expenses	$21,000

Insurance expenses	$6,000
Depreciation expenses	$15,000
Total fixed expenses		$90,000
Net operating income		$30,000

Explanation of Solution

1. If the total amount of any expenses does not changes at different level of sales, it is a fixed expenses and if the total amount of any expenses changes at different level of sales, it is a variable expenses or mixed expenses. The combination of fixed and variable expenses is called a mixed expense.

2.

Applying High-low method to Shipping expenses (Mixed expenses)

	Units	Shipping Expenses
High Activity level	5,000	$38,000
Low Activity level	4,000	$34,000
Change	1,000	$4,000

  $\begin{array}{l}Variableexpensesperunit=\frac{Changeofcost}{Changeinactivity}\hfill \\ =\frac{\$4,000}{1,000units}\hfill \\ =\$4perunit\hfill \end{array}$

  $$

Computation of Fixed cost at highest level of activity

  $\begin{array}{l}\begin{array}{l}Fixedcost=Totalcost–\left(VariablecostperunitXhighestlevelofactivity\right)\\ FixedCost=\$\text{ 38,000 }–\left(\$\text{ 4 X 5,000}\text{units}\right)\end{array}\hfill \\ =\$\text{ 38,000 }–\text{ \$20,000}\hfill \\ =\$18,000\hfill \end{array}$

Applying High-low method to Salaries and commissions expenses (Mixed expenses)

	Units	Shipping Expenses
High Activity level	5,000	$90,000
Lowest Activity level	4,000	$78,000
Change	1,000	$12,000

  $\begin{array}{l}Variableexpensesperunit=\frac{Changeofcost}{Changeinactivity}\hfill \\ =\frac{\$12,000}{1,000units}\hfill \\ =\$12perunit\hfill \end{array}$

Computation of fixed cost at highest level of activity

  $\begin{array}{l}\begin{array}{l}Fixed\text{ C}ost=Totalcost–\left(VariablecostperunitXhighestlevelofactivity\right)\\ FixedCost=\$\text{ 90,000 }–\left(\$\text{12 X 5,000}\text{units}\right)\end{array}\hfill \\ =\$\text{ 90,000 }–\text{ \$60,000}\hfill \\ =\$30,000\hfill \end{array}$

3. The mixed expenses are distributed according to the variable and fixed elements based upon the figures computed by High-low Method. The variable expenses are $4 for shipping expenses and $12 for salaries and commissions. The fixed expenses are $18,000 for shipping expenses and $30,000 for salaries and commissions. The fixed expenses and variable expenses per unit will always remain the same for any level of sale.
