Genesis went shopping for holiday presents. She bought boxes of chocolates and boxes of ornaments for her coworkers. Boxes of chocolate cost \( \$ 10 \) each and boxes of ornaments cost \( \$ 6 \) each. She buys a total of 16 boxes and spends \( \$ 120 \). How many boxes of chocolates and how many boxes of ornaments does she buy? Using \( C \) for number of chocolate bcyxes and \( O \) for number of ornament boxes. Setup but do not solve the equations necessary to answer the questions. Your 1st equation: Your 2nd equation:
