Answer
Explanation:
Step1: Calculate the markup amount
Markup amount = Selling price - Cost price. Here, selling price = $9 and cost price = $6. So, Markup amount = $9 - $6 = $3.
Step2: Calculate the percentage markup
Percentage markup = $\frac{\text{Markup amount}}{\text{Cost price}}\times100%$. Substitute the values: $\frac{3}{6}\times100% = 50%$.
Answer:
A. 50%
