Q: Nathan wants to line the inside of a box with velvet. The box has two long sides that measure 8 inches by 6 inches, two short sides that measure 5 inches by six inches and a top and a bottom that each measure 40 square inches. How many square inches of velvet does Nathan need?
A: First find the area of each long side by multiplying the length and width: 8 inches * 6 inches = 48 square inches. Then do the same thing for each short side: 5 inches * 6 inches = 30 square inches. Now add the area of one long side, one short side, and one top / bottom together: 48 square inches + 30 square inches + 40 square inches = 118 square inches. Now double that quantity because there are two of each kind of side: 118 square inches * 2 = 236 square inches. The answer is 236.

Q: Bob drove for one and a half hours at 60/mph. He then hit construction and drove for 2 hours at 45/mph. How many miles did Bob travel in those 3 and a half hours?
A: Bob drove for 1.5 hour * 60 / mph = 90 miles. Bod drove for 2 hour * 45 / mph = 90 miles. In total Bob drove 90 + 90 miles = 180 miles. The answer is 180.

Q: A waterpark opens up and charges $30 for admission. Kids' tickets are half price. If a group of people brings a soda, they can get 20% off the total price of admission. Janet gets tickets for 10 people and 4 of them are children. She buys a soda for $5 to take advantage of the discount for her group. How much did she pay for everything?
A:
She bought 10 - 4 = 6 adult tickets. So 6 * 30 = $180 was the cost for adult tickets. Children tickets cost 30 / 2 = $15 each. So the children tickets cost 15 * 4 = $60. So the total cost of tickets is 60 + 180 = $240. They get a 240 * .2 = $48 discount. So the tickets cost 240 - 48 = $192. So in total she paid 192 + 5 = $197. The answer is 197.
