Label your matrices "Game 1" and "Game 2." (2 points: 1 point for each matrix) B. Add your matrices from part A to find the total number sold for each food item. Label the answer matrix "Games 1 and 2." Show your work and interpret your answer. (3 points: 2 points for answer matrix and 1 point for interpretation)
