Betsy won 5 games of Monopoly. Helen won twice as many as Betsy and Susan won three times as many as Betsy. Between them, how many games have they won?
Thoughts? Step-by-step reasoning:
Helen won twice as many games as Betsy's 5 so Helen won 2 * 5 = 10 games. Susan won three times as many games as Betsy's 5 so Susan won 3 * 5 = 15 games. When you combine their wins, together they won 5 + 10 + 15 = 30 games total.
Thus, the answer is 30.
