<prompt> Human: Im a high school football player, and we were given 25 coupon cards worth 20 dollars each 500 in total to sell as a fundraiser . Well, I lost my cards, and now I need to reimburse my already poorly funded team the money I lost. How can I make that much money somewhat quickly? I have about 2-3 weeks. Also, people who sell all 25 get 100 back out of the 500 for selling all their cards. So I guess technically I only need 400?  <response>: You may only be liable for the wholesale cost, not the resale cost, if you even have to pay anything at all. Remember, they probably bought these at like 5 a pop to sell them at 20 and make a profit.
