Take notes about your classmates’ approaches and explanations for solving the three percent decrease problems.

Hint:

As your classmates present, ask questions such as:

  • Where is the unknown amount in your equation?
  • Why does your solution make sense in this situation?
  • Should the solution be greater than or less than the given amount?
  • Should the solution be greater than or less than 100%?
  • How did you use the mathematical structure of the situation to help you solve the problem?
  • How is solving a percent decrease problem similar to solving a percent increase problem? How is it different?
