Final answer:
To determine the common size percents for operating expenses in Year 2 and Year 1, divide the operating expenses by the net sales and multiply by 100%.
Step-by-step explanation:
To determine the Year 2 and Year 1 common size percents for operating expenses using net sales as the base, we need to divide the operating expenses by the net sales and multiply by 100%.
For Year 2, the operating expenses are $88,240 and the net sales are $604,200. So, the Year 2 common size percent for operating expenses would be:
Year 2 common size percent for operating expenses = (operating expenses / net sales) * 100%
Year 2 common size percent for operating expenses = ($88,240 / $604,200) * 100%
For Year 1, the operating expenses are $85,040 and the net sales are $487,400. So, the Year 1 common size percent for operating expenses would be:
Year 1 common size percent for operating expenses = (operating expenses / net sales) * 100%
Year 1 common size percent for operating expenses = ($85,040 / $487,400) * 100%
