To find the markup, substract the price at which the car was bought from the price at which the car was sold:
[tex]26,808-20,480=6328[/tex]To find the markup as a percentage from the original price, set 20,480 to be equal to 100%. If x% represents 6328, then:
[tex]\begin{gathered} \frac{x}{6328}=\frac{100}{20,480} \\ \Rightarrow x=\frac{100\times6328}{20,480}=30.898\ldots \end{gathered}[/tex]To the nearest tenth, 30.898... = 30.9.
Therefore, the markup is equal to 30.9%.
