Given:

Cost of fish dinner = $10.95

selling price of fish dinner = $13.95.

To find:

The percent markup.

Solution:

We know that,

$\text{Percent Markup}=\dfrac{\text{Price - Cost}}{\text{Cost}}\times 100$

Using this formula, we get

$\text{Percent Markup}=\dfrac{13.95-10.95}{10.95}\times 100$

$\text{Percent Markup}=\dfrac{3}{10.95}\times 100$

$\text{Percent Markup}=\dfrac{300}{10.95}$

$\text{Percent Markup}=27.39726$

Round to the one decimal place.

$\text{Percent Markup}\approx 27.4$

Therefore, the markup is 27.4%.
