Final answer:
When preparing common size financial statements, the interest expense would be shown as a percentage of the sales. In this case, the correct percentage is 5.2%.
Step-by-step explanation:
When preparing common size financial statements, the interest expense would be shown as a percentage of the sales. To find the percentage, you can divide the interest expense ($65,000) by the sales ($1,250,000) and multiply by 100:
Interest Expense as a percentage = (Interest Expense / Sales) x 100
Plugging in the values, we get:
Interest Expense as a percentage = (65000 / 1250000) x 100 = 5.2%
Therefore, the correct answer is option C) 5.2%.
