Answer:
C. 76.3%
Explanation:
To find Korey's gross profit margin, we can use the formula:
Gross Profit Margin = (Gross Profit / Net Sales) x 100%
We are given that Korey's net sales were $4,350 and gross profit was $3,320. Plugging these values into the formula, we get:
Gross Profit Margin = ($3,320 / $4,350) x 100%
Gross Profit Margin = 0.763 x 100%
Gross Profit Margin = 76.3%
Therefore, Korey's gross profit margin is c. 76.3%
