I'll give you a question, please answer with step-by-step reasoning process.
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?

15
Let x represent the amount that Pop spent in $.

Crackle: 3x.

Snap:2(3x) = 6x.

x + 3x + 6x = 150.

10x = 150.

x = 15.

.

The final answer: 15
