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 be accurate as possible and think first.
84
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
