Answer:
The answer is 67.75 percent
Step-by-step explanation:
Gross profit margin is a measure of profitability.
Gross margin ratio = (gross profit ÷ net revenue/sales) x 100 percent.
Gross profit = net sales - cost of sales
Net sales - $678,400
Cost of sales - $218,810
Gross profit = $678,400- $218,810
= $459,590
Now gross margin ratio:
($459,590/$678,400) x 100 percent
= 67.75 percent
