conversations.value: Explain how to solve this math problem: Cappuccinos cost $2, iced teas cost $3, cafe lattes cost $1.5 and espressos cost $1 each. Sandy orders some drinks for herself and some friends. She orders three cappuccinos, two iced teas, two cafe lattes, and two espressos. How much change does she receive back for a twenty-dollar bill?

conversations.value: Find the total cost of the cappuccinos by multiplying the price by the quantity: 3 cappuccinos x $2/cappuccino = $6
  Then do the same for the iced teas: 2 iced teas x $3/tea = $6
  Then do the same for the cafe lattes: 2 lattes x $1.5/latte = $3
  Then do the same for the espressos: 2 espressos x $1 = $2
  In total Sandy pays $6 + $6 + $3 + $2 = $17
  Sandy will receive $20 - $17 = $3 in change
