[Question]The total number of lions in a park is twice the number of leopards in the same park. The number of elephants is half the combined number of lions and leopards. Calculate the total population of the three animals in the park if the number of lions is 200.
[Answer]If there are 200 lions in the park, which is twice the number of leopards in the park, there are 200 / 2 = 100 leopards in the park. The total population of lions and leopards in the park is 200 lions + 100 leopards = 300. The number of elephants in the park is 1 / 2 the total population of lions and leopards; thus, there are 300 / 2 = 150 elephants in the park. There are a total of 150 + 300 = 450 animals in the park. The answer is 450.
Q: The first store charges $3 for 6 apples while the second store charges $4 for 10 apples. How many cents can you save on each apple from buying $4 for 10 apples than from $3 for 6 apples?
A: In the first store, each apple costs $3 / 6 = $0.5. In the second store, each apple costs $4 / 10 = $0.4. So, you can save $0.5 - $0.4 = $0.1 on each apple from buying $4 for 10 apples than from $3 for 6 apples. In cents, this is equal to $0.1 x 100 = 10. The answer is 10.

Q: There are twice as many cows in Devonshire as there are hearts on a standard deck of 52 playing cards. If there are 4 hearts on a card, calculate the total cost of the cows when they are sold at $200 each.
A: If there are 4 hearts on a card, a standard deck of 52 playing cards will have 208 hearts. There are twice as many cows in Devonshire as there are hearts on a standard deck of 52 playing cards, meaning there are 2 * 208 = 416 cows in Devonshire. The total cost of the cows when they are sold at $200 each is 416 * $200 = $83200. The answer is 83200.
Question: In a restaurant, a burger costs $9, and a pizza twice as much. How much would cost one pizza and three burgers?
Answer:
One pizza costs twice as much as the burger, which means 9 * 2 = $18. Three burgers would cost 9 * 3 = $27. So one pizza and three burgers would cost in total 18 + 27 = $45. The answer is 45.
