Question: There are twice as many cows as dogs at a petting farm. If there are currently 184 cows at the farm, and the farm owner decides to sell 1/4 of the cows and 3/4 of the dogs, how many animals are remaining on the farm?
Answer: If there are 184 cows, twice the number of dogs, then there are 184 / 2 = 92 dogs on the farm. When the farm owner decided to sell 1 / 4 of cows, he sold 1 / 4 * 184 = 46 cows. The total number of cows remaining on the farm is 184 - 46 = 138. If the farm owner also sold 3 / 4 of the dogs, he sold 3 / 4 * 92 = 69. The total number of dogs remaining on the farm is 92 - 69 = 23. The total number of animals remaining on the farm is 23 + 138 = 161. The answer is 161.

Q: Josh is saving up for a box of cookies. To raise the money, he is going to make bracelets and sell them. It costs $1 for supplies for each bracelet and he sells each one for $1.5. If he makes 12 bracelets and after buying the cookies still has $3, how much did the box of cookies cost?
A: He makes $.5 profit on each bracelet because 1.5 - 1 = .5. He earns $6 because 12 x .5 = 6. The cookies cost $3 because 6 - 3 = 3. The answer is 3.
Question: There are 360 balls in the ball pit. If a quarter of the balls in the ball pit are red and a fifth of the remaining balls are blue. How many of the balls are neither red nor blue?
Answer: A quarter of the balls are red and therefore there are 360 x (1 / 4) = 90 red balls. When you remove the red balls from the ball pit there are 360 - 90 = 270 remaining balls. A fifth of the remaining balls are blue, and therefore there are 270 x (1 / 5) = 54 blue balls. The total of red and blue balls equals 90 + 54 = 144 balls. When you remove the red and blue balls from the total there are 360 - 144 = 216 balls that are neither red nor blue. The answer is 216.
[Question]A Moroccan restaurant received 3 different shipments of couscous. The first two shipments of 7 and 13 pounds arrived on the same day. The next day's shipment was 45 pounds of couscous. If it takes 5 pounds of couscous to make a dish, how many dishes did the restaurant make?
[Answer]The first two shipments of couscous added up to 7 + 13 = 20 pounds. Adding that weight to the next day’s shipment results in a total weight of 20 + 45 = 65 pounds. Since each dish takes 5 pounds, then the restaurant makes 65 / 5 = 13 dishes. The answer is 13.
[Question]Shara borrowed money from her brother 6 months ago. She returned $10 per month to her brother. Currently, she was able to return half of the money she borrowed. How much will she still owe her brother 4 months from now?
[Answer]
For 6 months, Shara was able to return $10 x 6 = $60 to her brother. Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now. The answer is 20.
