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?

conversations.value: 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.
