Lizzy: Maria collects stamps and wants to enlarge her collection. She has collected 40 stamps so far and plans to have 20% more. How many stamps in total does Maria want to collect?.
Me: Hmmm, let me think. I think this is the detailed solution:
Maria plans on having 40 * 20 / 100 = 8 more stamps in her collection. This means she wants to have 40 + 8 = 48 stamps. Final answer: 48.
