Answer this question:Kelly needs school supplies to teach her class for an art project. She has 8 students and they will need 3 pieces of construction paper each. In addition to the construction paper, she needs to buy 6 bottles of glue for everyone to share. After Kelly purchases these supplies, she dropped half of them down a storm drain. Class is about to start, but she manages to rush to the store and buy 5 more pieces of construction paper. How many supplies are left?
Kelly needs 8 * 3 = 24 pieces of construction paper. She buys glue which grows the supplies to 24 + 6 = 30. Unfortunately, she dropped 30 / 2 = 15 supplies. Rushing to the store, she buys more construction paper bringing her supplies back to 15 + 5 = 20.
The answer is 20.

Answer this question:A carton contains 12 boxes. If each box has 10 packs of cheese cookies, what's the price of a pack of cheese cookies if a dozen cartons cost $1440?
If 1 carton contains 12 boxes, then a dozen cartons contain 12 * 12 = 144 boxes. If 1 box has 10 packs of cookies, then 144 boxes have 144 * 10 = 1440 packs. If a dozen cartons cost $1440 and contain 1440 packs of cookies, then each pack costs 1440 / 1440 = $1.
The answer is 1.

Answer this question:The price of a math textbook in the school bookshop is $45. If those sold in bookshops outside the school cost 20% less, how much can Peter save by buying from other bookshops rather than the school's if he wants to buy 3 math textbooks?
20% of $45 is (20 / 100) * $45 = $9. The price of the textbook in other bookshops cost $9 less than $45 which is $45 - $9 = $36. Three textbooks from the school bookshop would cost $45 * 3 = $135. Three textbooks from another bookshop would cost $36 * 3 = $108. Peter can save $135 - $108 = $27 by buying from another bookshop.
The answer is 27.
