Lizzy: Sean buys 3 cans of soda, 2 soups, and 1 sandwich. Each soup cost as much as the 3 combined sodas. The sandwich cost 3 times as much as the soup. If the soda cost $1 how much did everything cost together?.
Me: Hmmm, let me think. I think this is the detailed solution:
The soda cost 3 * 1 = $3. So the soups cost 2 * 3 = $6. The sandwich cost 3 * 3 = $9. So the total cost of everything was 3 + 6 + 9 = $18. Final answer: 18.
