"Genatron wants to estimate what will happen to its income before interest and taxes if its net sales change from the 2012 level of $1,500,000. Refer to Genatron’s 2012 income statement below, where the income before interest and taxes is $247,000 (EBT of $190,000 plus Interest of $57,000). Assume that the cost of goods sold are variable expenses and that the other operating expenses are fixed.

"
Calculate the expected amount of income before interest and taxes for both a 10 percent decrease and a 10 percent increase in net sales for next year.

To calculate the expected amount of income before interest and taxes for a 10 percent decrease and a 10 percent increase in net sales for next year, we need to follow these steps:

1. Calculate the 10 percent decrease and 10 percent increase in net sales:
- For a 10 percent decrease: 1,500,000 * (1 - 0.10) = 1,350,000
- For a 10 percent increase: 1,500,000 * (1 + 0.10) = 1,650,000

2. Calculate the cost of goods sold (variable expenses) based on the net sales figure:
- Cost of goods sold = Net sales * Cost of goods sold as a percentage of net sales (variable expense ratio)
Since the statement does not provide the variable expense ratio, we can assume it to be constant at 60% (900,000/1,500,000).

- For the 10 percent decrease: 1,350,000 * 60% = 810,000
- For the 10 percent increase: 1,650,000 * 60% = 990,000

3. Calculate the gross profit:
- Gross profit = Net sales - Cost of goods sold
- For the 10 percent decrease: 1,350,000 - 810,000 = 540,000
- For the 10 percent increase: 1,650,000 - 990,000 = 660,000

4. Calculate the income before interest and taxes (EBT):
- Income before interest and taxes = Gross profit - Other operating expenses (fixed expenses)
In the given statement, we have general & administrative expenses, marketing expenses, and depreciation as fixed expenses.

- For the 10 percent decrease:
Income before interest and taxes = 540,000 - (150,000 + 15,000 + 3,000) = 372,000

- For the 10 percent increase:
Income before interest and taxes = 660,000 - (150,000 + 15,000 + 3,000) = 492,000

Now, to calculate the percentage change in income before interest and taxes and the degree of operating leverage:

Percentage Change in Income Before Interest and Taxes:
- For the 10 percent decrease: (372,000 - 247,000) / 247,000 * 100 = 50.61%
- For the 10 percent increase: (492,000 - 247,000) / 247,000 * 100 = 99.59%

Degree of Operating Leverage:
- The degree of operating leverage (DOL) can be calculated using the following formula:
DOL = Percentage Change in Income Before Interest and Taxes / Percentage Change in Net Sales
- For the 10 percent decrease: 50.61% / -10% = -5.06
- For the 10 percent increase: 99.59% / 10% = 9.96

Therefore, the expected percentage change in income before interest and taxes is 50.61% for a 10 percent decrease in net sales and 99.59% for a 10 percent increase in net sales. The degree of operating leverage is -5.06 for a 10 percent decrease and 9.96 for a 10 percent increase.
