A concert ticket costs $40. Mr. Benson bought 12 tickets and received a 5% discount for every ticket bought that exceeds 10. How much did Mr. Benson pay in all? Let's think first. Chain of thought:
Mr. Benson had a 5% discount for each of the 12 - 10 = 2 tickets. So, those two tickets had a $40 x 5 / 100 = $2 discount each. Hence, each ticket cost $40 - $2 = $38 each. Thus, two discounted tickets amount to $38 x 2 = $76. And the other ten tickets amount to $40 x 10 = $400. Hence, Mr. Benson paid a total of $400 + $76 = $476.
Therefore, the answer is 476.
