Explain simply why 2 is the correct answer to: Reggie and his brother are having a basketball shooting contest. They each get to take 10 shots. Layups are worth 1 point, free throws are worth 2 points, and anything further away is worth 3 points. Reggie makes 3 layups, two free throws, and one long shot. His brother only shoots long shots and makes 4 of them. How many points does Reggie lose by?. Explanation:
Reggie makes 3 points off layups because 3 x 1 = 3. Reggie makes 4 points off free - throws because 2 x 2 = 4. Reggie makes 3 points off long shots because 1 x 3 = 3. Reggie scores 10 points because 3 + 4 + 3 = 10. His brother scores 12 points because 4 x 3 = 12. Reggie loses by 2 because 12 - 10 = 2.
