Snap, Crackle, and Pop spend $150 on cereal in a grocery store. Snap spends twice as much as Crackle. Crackle spends 3 times as much as Pop. How much did Pop spend? Think carefully first, then make a decision:
Let x represent the amount that Pop spent in $. Crackle: 3x. Snap:2(3x) = 6x. x + 3x + 6x = 150. 10x = 150. x = 15. So, the answer is 15.
