During 5 hours, a spider can catch 9 flies. How many flies would this spider catch in 30 hours if he would keep his efficiency?
Let's think: 30 hours is 30 / 5 = 6 times more time. So the spider would be able to catch 6 * 9 = 54 flies.. The answer is: 54.

Avery has 20 chickens on his farm. Each chicken lays 6 eggs. He wants to fill up egg cartons with eggs. If each egg carton can hold a dozen (12 eggs), how many egg cartons can Avery fill?
Let's think: Avery has a total of 20 * 6 = 120 eggs. Avery can fill up 120 / 12 = 10 egg cartons.. The answer is: 10.

Today Geoff bought 2 pairs of sneakers and spent $60 equally between the two. Tomorrow, he's going to spend 4 times as much on sneakers than he did on Monday. Wednesday, he'll spend 5 times as much on sneakers than he did on Monday. How much will Geoff spend on sneakers over these three days?
Let's think: Tomorrow Geoff will spend 60 * 4 = 240 dollars. Wednesday Geoff will spend 60 * 5 = 300 dollars. Total spent in three days is 60 + 240 + 300 = 600 dollars.. The answer is: 600.

There are 50 passengers on a bus. At the first stop, 16 more passengers get on the bus. On the other stops, 22 passengers get off the bus and 5 passengers more get on the bus. How many passengers are there on the bus in total at the last station?
Let's think:
There are 50 + 16 = 66 passengers at first. Then 66 - 22 = 44 passengers remain. Since 5 more passengers get on the bus there are 44 + 5 = 49 passengers on the bus.. The answer is: 49.
