Question: Joseph wants to go to Boston for a road trip. If he takes route A, it will take him 5 hours to arrive; but if he takes route B, it will only take him 2 hours to arrive at his destination. How much time will he save if he takes route B to Boston and back to his home?
Answer: He will spend 5 x 2 = 10 hours if he takes route A. Meanwhile, he will spend 2 x 2 = 4 hours if he takes route B. Therefore, Joseph can save 10 - 4 = 6 hours if he takes route B both ways. The answer is 6.
[Question]Sara and Joe have a combined height of 120 inches. Joe is 6 inches more than double Sara's height. How tall is Joe?
[Answer]Let x be Sara's height in inches. Joe is 6 + 2x inches tall. 120 = x + (6 + 2x). 120 = 3x + 6. 114 = 3x. x = 38 inches. Joe is 6 + 2(38) = 82 inches. The answer is 82.
Q: The difference between the ages of two friends is 2 years. The sum of their ages is 74 years. Find the age of the older friend.
A: Let X be the age of the older friend. The younger friend is X - 2 years old. So, the age of both is X + (X - 2) = 74. X + X = 74 + 2. 2 * X = 76. Then, the older friend is X = 38 years old. The answer is 38.
Question: Belle eats 4 dog biscuits and 2 rawhide bones every evening. If each rawhide bone is $1, and each dog biscuit is $0.25, then how much does it cost, in dollars, to feed Belle these treats for a week?

[Question]Janet counts 30 crows on the powerlines and 60% more hawks than crows. How many birds does she count total?
[Answer]First find how many more hawks than crows there are: 60% * 30 crows = 18 crows. Then add that number to the number of crows to find the total number of hawks: 18 crows + 30 crows = 48 crows. Then add the number of crows to the number of hawks to find the total number of birds: 48 crows + 30 crows = 78 crows. The answer is 78.
[Question]Mrs. Lim milks her cows twice a day. Yesterday morning, she got 68 gallons of milk and in the evening, she got 82 gallons. This morning, she got 18 gallons fewer than she had yesterday morning. After selling some gallons of milk in the afternoon, Mrs. Lim has only 24 gallons left. How much was her revenue for the milk if each gallon costs $3.50?
[Answer]
Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616. The answer is 616.
