Q: Deborah has four letters to mail. Standard postage is $1.08 per letter, with an additional charge for international mail. Deborah is mailing two letters internationally, and she is paying $4.60 to mail four letters. How many cents is the additional charge per letter for international shipping?
A: A dollar is 100 cents, so standard postage is 108 cents. Deborah’s four letters cost 108 * 4 = 432 cents for standard postage. She paid 460 - 432 = 28 cents for international shipping on two letters. Thus, the additional international shipping charge is 28 / 2 = 14 cents per letter. The answer is 14.
Question: When Erick went to the market to sell his fruits, he realized that the price of lemons had risen by $4 for each lemon. The price of grapes had also increased by half the price that the price of lemon increased by per grape. If he had planned to sell the lemons at $8 and the grapes at $7, and he had 80 lemons and 140 grapes in his basket, how much money did he collect from selling the fruits at the new prices?
Answer: The new price for each lemon after increasing by $4 is $8 + $4 = $12. For the 80 lemons, Erick received $12 * 80 = $960. The price of each grape increased by 1 / 2 * $4 = $2. The new price at which Erick sold his grapes is $7 + $2 = $9. For the 140 grapes, Erick collected 140 * $9 = $1260. From the sale of all of his fruits, Erick received $1260 + $960 = $2220. The answer is 2220.

Q: In the final game of the basketball season, four players scored points. Chandra scored twice as many points as did Akiko. Akiko scored 4 more points than did Michiko, and Michiko scored half as many points as did Bailey. If Bailey scored 14 points, how many points in total did the team score in the final game of the season?
A: If Bailey scored 14 points, and Michiko scored half as many points as Bailey, then Michiko scored 14 / 2 = 7 points. If Akiko scored 4 more points than did Michiko, then Akiko scored 7 + 4 = 11 points. Since Chandra scored twice as many points as did Akiko, then Chandra scored 11 * 2 = 22 points. Thus, in total, the team scored 14 + 7 + 11 + 22 = 54 points in total during the final game of the season. The answer is 54.
Question: 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?
Answer: 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: Susan has 3 fish tanks to fill. 1 fish tank contains 7 goldfish and 8 beta fish. The second fish tank contains twice as many fish as the first tank and the third fish tank has a third of the number of fish in the second fish tank. How many fish are in the third fish tank?
A:
In the first fish tank, there are 7 goldfish + 8 beta fish = 15 fish. The second fish tank therefore has 15 fish in the first tank * 2 = 30 fish. So the third tank has 30 fish in the second fish tank / 3 = 10 fish. The answer is 10.
