Question: In one of the building blocks at Oakland High there are 5 classes. Each class uses 2 whiteboards each and each whiteboard needs about 20ml of ink for a day's use. If ink costs 50 cents per ml, how much (in dollars) would it cost to use the boards for one day?
Answer: Each ml of ink costs 50 cents so 20 ml costs 20 * 50 = 1000 cents. There are 2 whiteboards in each class so each class needs 2 * 1000 cents = 2000 cents. There are five classes in the block so they all need 5 * 1 * 2000 cents = 10000 cents. 100 cents make a dollar so 10000 cents make 10000 / 100 = $100. The answer is 100.
[Question]Anna goes trick-or-treating in a subdivision where she gets 14 pieces of candy per house. Her brother Billy goes trick-or-tricking in a neighboring subdivision where he gets 11 pieces of candy per house. If the first subdivision has 60 houses and the second subdivision has 75 houses, how many more pieces of candy does Anna get?
[Answer]First find the total number of pieces of candy Anna gets: 14 pieces / house * 60 houses = 840 pieces. Then find the total number of pieces of candy Billy gets: 11 pieces / house * 75 houses = 825 pieces. Then subtract the number of pieces Billy gets from the number Anna gets to find the difference: 840 pieces - 825 pieces = 15 pieces. The answer is 15.
Q: Janet bought some muffins at the bakery. Each muffin is 75 cents. Janet paid $20 and got $11 in change back. How many muffins did Janet buy?
A: Janet paid with $20 and got back $11, so her muffins cost $20 - $11 = $9. Each muffin cost 75 cents, so she bought 9 / .75 = 12 muffins. The answer is 12.
Question: In four years, Annika will be three times as old as Hans. If Hans is now 8 years old, how old is Annika now?
Answer:
In four years, Hans will be 8 + 4 = 12 years old. Then Annika will be 12 * 3 = 36 years old. So Annika right now is 36 - 4 = 32 years old. The answer is 32.
