Lizzy: Marty and Biff were both running for student council president. A poll was taken to see how the candidate’s campaigns were going. 45% of the people polled said they were voting for Biff and 8% were undecided. The rest said they are voting for Marty. If 200 people were polled, how many said they are voting for Marty?.
Me: Hmmm, let me think. I think this is the detailed solution:

If 45% of people were voting for Biff + 8% were undecided = 53% were not voting for Marty. There were 100 – 53 = 47% voting for Marty. If 47% of 200 people were voting for Marty, 0.47 x 200 = 94 people said they were voting for Marty. Final answer: 94.
