conversations.value: Luke pays a school fee. His mother gave him one $50 bill, two $20 bills, and three $10 bills. His father gave him four $50 bills, one $20 bill, and one $10 bill. If his parents gave him the exact amount for the school fee, how much is the school fee?

conversations.from: assistant
conversations.value: Luke's parents gave him 1 + 4 = 5 $50 bills.
  These $50 bills amount to $50 x 5 = $250.
  His parents gave him 2 + 1 = 3 $20 bills.
  These $20 bills amount to $20 x 3 = $60.
  His parents gave him 3 + 1 = 4 $10 bills.
  These $10 bills amount to $10 x 4 = $40.
  Therefore, Luke's school fee is $250 + $60 + $40 = $350.
