Q: Walter goes to the zoo, where he spends a certain amount of time looking at the seals, eight times as long looking at the penguins, and 13 minutes looking at the elephants. If he spent 2 hours and 10 minutes at the zoo, how many minutes did he spent looking at the seals?
A: First find the number of minutes in 2 hours: 2 hours * 60 minutes / hour = 120 minutes. Then add 10 minutes to that amount to find the total number of minutes Walter spent at the zoo: 120 minutes + 10 minutes = 130 minutes. Let s be the amount of time he spends looking at the seals and p be the amount of time he spends looking at the penguins. From the problem, we know that s + p + 13 = 130 and p = 8s. Substituting the second equation into the first, we get s + 8s + 13 = 130. Combining like terms, we get 9s + 13 = 130. Subtracting 8 from both sides, we get 9s = 117. Dividing both sides by 9, we get s = 13. The answer is 13.
Question: Johnny is buying planks of wood to build some tables. Each table needs a plank of wood for each of the legs and 5 planks of wood for the surface. If Johnny wants to build 5 tables, how many planks of wood does he need?
Answer: Each table needs 1 plank of wood * 4 legs = 4 planks of wood for the legs. This means each table needs 4 planks of wood for legs + 5 planks of wood for the surface = 9 planks of wood. To build 5 tables, Johnny will therefore need 9 planks of wood * 5 tables = 45 planks of wood. The answer is 45.
[Question]Anne drops a mirror and breaks it into 60 pieces. She sweeps up half of them, then her cat steals 3 pieces and her boyfriend picks up 1/3 of the remaining pieces. How many pieces does her boyfriend pick up?
[Answer]First find the number of pieces left after Anne sweeps up: 60 pieces / 2 = 30 pieces. Then subtract the number her cat takes: 30 pieces - 3 pieces = 27 pieces. Divide that number by 3 to find how many pieces her boyfriend picks up: 27 pieces / 3 = 9 pieces. The answer is 9.
Q: Jerry mows 8 acres of lawn each week. He mows ¾ of it with a riding mower that can cut 2 acres an hour. He mows the rest with a push mower that can cut 1 acre an hour. How long does Jerry mow each week?
A: Jerry mows 8 acres x ¾ = 6 acres with a riding mower. It will take him 6 acres / 2 each hour = 3 hours. Jerry mows 8 acres – 6 acres mowed with a riding mower = 2 acres with a push mower. It will take him 2 acres x 1 hour = 2 hours. It takes Jerry a total of 3 hours on the riding mower + 2 hours on the push mower = 5 hours. The answer is 5.
Question: Four years ago, Kody was only half as old as Mohamed. If Mohamed is currently twice 30 years old, how old is Kody?
Answer: Mohammed is currently 2 * 30 = 60 years old. four years ago, Mohammed was 60 - 4 = 56 years old. Four years ago, Kody was half Mohammed's age, which is 56 / 2 = 28 years old. Currently, Kody is 28 + 4 = 32 years old. The answer is 32.

Ryan owns $48 x 2 / 3 = $32 of the $48. While Leo owns $48 - $32 = $16 of the $48. Leo had $16 + $10 = $26 after Ryan paid him $10. But since he owed Ryan $7, then Leo has $26 - $7 = $19. The answer is 19.
