Lizzy: A school canteen sells a sandwich at $2, a hamburger at $2, one stick of hotdog at $1, and a can of fruit juice at $2 each can. Selene buys three sandwiches and a can of fruit juice. Tanya buys two hamburgers and two cans of fruit juice. How much do Selene and Tanya spend together?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
Three sandwiches cost 3 x $2 = $6. So, Selene spends $6 + $2 = $8. Two hamburgers cost 2 x $2 = $4. Two cans of fruit juice cost 2 x $2 = $4. Thus, Tanyah spends $4 + $4 = $8. Therefore, Selene and Tanya spend $8 + $8 = $16. Final answer: 16.
