To find the markup percentage, you can use the formula:
\[ \text{Markup Percentage} = \left( \frac{\text{Selling Price} - \text{Cost Price}}{\text{Cost Price}} \right) \times 100 \]
In this case:
- Cost Price = $50
- Selling Price = $80
Now, plug these values into the formula:
\[ \text{Markup Percentage} = \left( \frac{80 - 50}{50} \right) \times 100 \]
\[ \text{Markup Percentage} = \left( \frac{30}{50} \right) \times 100 \]
\[ \text{Markup Percentage} = 0.6 \times 100 = 60% \]
Therefore, the markup percentage is 60%.
