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?
Three sandwiches cost 3 x $2 = $<<3*2=6>>6.
So, Selene spends $6 + $2 = $<<6+2=8>>8.
Two hamburgers cost 2 x $2 = $<<2*2=4>>4.
Two cans of fruit juice cost 2 x $2 = $<<2*2=4>>4.
Thus, Tanyah spends $4 +$4 = $<<4+4=8>>8.
Therefore, Selene and Tanya spend $8 + $8 = $<<8+8=16>>16.
