 <translate> 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.
