Cost = $15
Selling Price = $24
The markup is the increased price expressed as a percentage of the cost.
The formula is:
![MU=(SP-C)/(C)*100](https://img.qammunity.org/2023/formulas/mathematics/college/pbkqcnj5fsilu9e4kshfgufbum4lsscpws.png)
Where
MU is the Markup
SP is the Selling Price
C is the Cost
Given,
SP = 24
C = 15, Let's figure out the Markup. Shown below:
![\begin{gathered} MU=(SP-C)/(C)*100 \\ MU=(24-15)/(15)*100 \\ MU=(9)/(15)*100 \\ MU=(3)/(5)*100 \\ MU=(300)/(5) \\ MU=60\% \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/pl83s4ott00wngky3lch8xtmrk77mqwjyj.png)
Thus, the markup rate is
60%
