Françoise sells pots of lily of the valley to fund humanitarian work. She buys them at €12 each and sells them at a 25% higher cost. How much will she give back to the association by selling 150 pots of lily of the valley?
The benefit of selling one pot is 12 * 25 / 100 = €<<12*25/100=3>>3.
So, Françoise will give 150 * €3 = €<<150*3=450>>450 to the association.
#### 450
