Kyle has $12 less than 3 times what Dave has. Kyle then spends a third of it going snowboarding. If Dave has $46, how much money does Kyle have? Let's think first. Chain of thought:
Kyle has 46 * 3 - 12 = 126 dollars. Kyle spends 126 / 3 = 42 dollars going snowboarding. Kyle has 126 - 42 = 84 dollars left.
Therefore, the answer is 84.
