Final answer:
The percentage of cost of goods sold (COGS) relative to sales for Upton Inc. in 2022 on a common size income statement is 46.25%. This is calculated by dividing the COGS by the total sales and then multiplying by 100%.
Step-by-step explanation:
To calculate the percentage of cost of goods sold (COGS) relative to sales on a common size income statement for Upton Inc. for the year ended December 31, 2022, we use the following formula:
Common size percentage for COGS = (COGS/Sales) × 100%
For the year 2022:
Common size percentage for COGS = ($370/$800) × 100% = 46.25%
Therefore, 46.25% would be attributable to the 2022 cost of goods sold of Upton Inc. on a common size income statement. This figure represents the proportion of each dollar of sales that is consumed by the cost of producing the goods.
