To solve the given questions, we will follow these approaches:
Break-even Point Calculation:
- Calculate the contribution margin per unit (selling price minus variable expenses).
- Determine the break-even point in units by dividing total fixed expenses by the contribution margin per unit.
- Calculate the break-even point in dollar sales by multiplying the break-even units by the selling price.
Effect of Increased Variable Expenses:
- Understand that an increase in variable expenses reduces the contribution margin per unit, which increases the break-even point in units.
Contribution Format Income Statements:
- Calculate the current contribution margin and net operating income.
- Adjust the selling price and sales volume according to the proposed changes and calculate the new contribution margin and net operating income.
The contribution margin per unit is calculated as:
\[
\text{Contribution Margin per Unit} = \text{Selling Price} - \text{Variable Expenses} = 100 - 70 = 30
\]
The break-even point in units is:
\[
\text{Break-even Units} = \frac{\text{Fixed Expenses}}{\text{Contribution Margin per Unit}} = \frac{150000}{30} = 5000
\]
The break-even point in dollar sales is:
\[
\text{Break-even Dollar Sales} = \text{Break-even Units} \times \text{Selling Price} = 5000 \times 100 = 500000
\]
If the variable expenses increase, the contribution margin per unit decreases, leading to a higher break-even point in units. This is because:
\[
\text{New Contribution Margin per Unit} = \text{Selling Price} - \text{Increased Variable Expenses}
\]
A decrease in the contribution margin results in:
\[
\text{Higher Break-even Units} = \frac{\text{Fixed Expenses}}{\text{New Contribution Margin per Unit}}
\]
\[
\text{Current Sales Revenue} = 16000 \times 100 = 1600000
\]
- Current Variable Expenses:
\[
\text{Current Variable Expenses} = 16000 \times 70 = 1120000
\]
- Current Contribution Margin:
\[
\text{Current Contribution Margin} = 1600000 - 1120000 = 480000
\]
- Current Net Operating Income:
\[
\text{Current Net Operating Income} = 480000 - 150000 = 330000
\]
\[
\text{New Selling Price} = 100 \times 0.9 = 90
\]
\[
\text{New Sales Units} = 16000 \times 1.25 = 20000
\]
\[
\text{New Sales Revenue} = 20000 \times 90 = 1800000
\]
\[
\text{New Variable Expenses} = 20000 \times 70 = 1400000
\]
\[
\text{New Contribution Margin} = 1800000 - 1400000 = 400000
\]
- New Net Operating Income:
\[
\text{New Net Operating Income} = 400000 - 150000 = 250000
\]
- Break-even point in units: \(\boxed{5000}\)
- Break-even point in dollar sales: \(\boxed{500000}\)
- Current Net Operating Income: \(\boxed{330000}\)
- New Net Operating Income after proposed changes: \(\boxed{250000}\)
