Mrs. Wang has presented her students with the following problem:
We have a quart of pure alcohol. If we add a cup of water to the alcohol, what percent of the new mixture is alcohol?
She then says, "Let's look at what we're given and what we want."
"We want the total amount of the mixture we have together," Robert suggests. After some discussion, the class decides that the mixture is 75% alcohol.
"I don't think that's right," Kathy observes. "We have 5 cups of mixture altogether, and only one of those cups is water."
