Kelly sold games and books. Games are sold for $9 each, while books arelisted at $6 each. If Kelly sold $171 and only sold 24 items. Write the system of equations that models this situation.

Answer 1

9G + 6B = 171

G+B = 24

9G+9B = 216

subtract to get

3B = 216-171 = 45

B =45/3 = 15 books sold

G = 24-15 = 9 games sold
