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? Let's answer step by step:
The benefit of selling one pot is 12 * 25 / 100 = €3. So, Françoise will give 150 * €3 = €450 to the association. The answer: 450.
