To calculate the profit margin, we divide the net income by net sales and express the result as a percentage:
Profit margin = (Net income / Net sales) x 100%
In this case, we have:
Net sales = $24,128
Net income = $2,223
Therefore:
Profit margin = ($2,223 / $24,128) x 100% = 9.2%
So the profit margin for Papa's Pizza for the past year is 9.2%.
