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? Let's answer step by step:
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. The answer: 350.
