Mixture problems are a classic in first-year algebra. Unfortunately, many learners approach them in a formulaic fashion and don't truly understand the meaning of the algebraic expressions they are using. Here, the questions are not the traditional ones, but rather questions that get students to think about what different parts of the equations represent. This is a good exercise in reasoning abstractly and quantiatively.
