An entrepreneur buys some carousel horses. Each one costs $750 and resells online for $990. What is the mark-up percentage?

Write your answer using a percent sign (%).

The mark-up amount is $990 - $750 = $<<990-750=240>>240.

The mark-up percentage is (240 / 750) * 100% ≈ 32%.
Therefore, the mark-up percentage is 32%.
