conversations.value: Tom wants to visit Barbados.  He needs to get 10 different vaccines to go and a doctor's visit.  They each cost $45 and the doctor's visit costs $250 but insurance will cover 80% of these medical bills.  The trip itself cost $1200.  How much will he have to pay?
  Give me a solution to this problem

conversations.value: The medical cost comes out to 45*10+250=$700
  Insurance covers 700*.8=$560
  So he has to pay 700-560=$140
  Added to the cost of the trip he has to pay 1200+140=$1340
