Lizzy: The school decided to have a fundraiser to collect $750 for new basketball equipment. Families could donate $25, $50, or $100. Families who donated $25 got Bronze Status. Families who donated $50 got Silver Status. Families who donated $100 got Gold Status. With one day left in the fundraiser, the school has 10 Bronze Status families, 7 Silver Status Families and 1 Gold Status family. How much do they need to raise on the final day to reach their goal?.
Me: Hmmm, let me think. I think this is the detailed solution:
They collected $250 from Bronze Status families because 10 times 25 equals 250. They collected $350 from Silver Status families because 7 times 50 equals 350. They collected $100 from Gold Status families because 1 times 100 equals 100. Therefore, they collected $700 thus far because 250 plus 350 plus 100 equals 700. They need to collect $50 more because 750 minus 700 equals 50. Final answer: 50.
