Lizzy: A school is adding 5 rows of seats to the auditorium. Each row has 8 seats and each seat costs $30. A parent, being a seat manufacturer, offered a 10% discount on each group of 10 seats purchased. How much will the school pay for the new seats?.
Me: Hmmm, let me think. I think this is the detailed solution:

Ten seats amount to $30 x 10 = $300. So there is $300 x 10 / 100 = $30 discount for each 10 seats purchased. Thus, the total cost for every 10 seats is $300 - $30 = $270. The school is going to buy 5 x 8 = 40 seats. This means that the school is going to buy 40 / 10 = 4 sets of 10 seats. Therefore, the school will pay a total of $270 x 4 = $1080 for the new seats. Final answer: 1080.
