To determine the mark-up percentage, we need to calculate the difference between the selling price and the cost price as a percentage of the cost price.

The cost price of each fountain is $25, and it is resold online for $57. The mark-up is the difference between the selling price and the cost price, which in this case is $57 - $25 = $32.

To find the mark-up percentage, you can use the following formula:
Mark-up percentage = (Mark-up / Cost price) × 100

Let's calculate it:
Mark-up percentage = ($32 / $25) × 100
Mark-up percentage = 1.28 × 100
Mark-up percentage = 128%

Therefore, the mark-up percentage on these fountains is 128%.
