Q: Betty bought 1 kg of oranges and 3 kg of apples. The total cost of oranges was $12. The apples were two times cheaper than the oranges. How much did Betty pay for 1 kg of apples?
A: The cost of the apples was $12 / 2 = $6. When the cost of 3 kg of apples was $6, then the cost of 1 kg of apples was $6 / 3 kg = $2 / kg. The answer is 2.
Question: Jess made 3 different stacks of wooden blocks. The first stack was 7 blocks high, the second stack was 5 block(s) higher than the first, and the final stack was 7 block(s) higher than the second. Jess' little sister knocked over the entire first tower, in the second tower she left 2 blocks standing, and in the final tower she left 3 blocks standing. How many blocks in total fell down?
Answer: Jess' second stack was 7 blocks + 5 blocks = 12 blocks. Jess' third stack was 12 blocks + 7 blocks = 19 blocks high. Jess' sister knocked down the second tower and knocked 12 blocks 2 = 10 blocks knocked over. Jess' sister knocked down the final tower and knocked 19 blocks 3 = 16 blocks knocked over. Total blocks knocked over was 7 blocks + 10 + 16 = 33 blocks. The answer is 33.
[Question]Andrew's dog has 12 burrs and six times as many ticks as burrs. How many foreign objects total are caught in the dog's fur?
[Answer]First find how many burrs are caught in the dog's fur: 12 burrs * 6 ticks / burr = 72 ticks. Then add the number of burrs to find the total number objects: 72 objects + 12 objects = 84 objects. The answer is 84.
Q: Carson is a night security guard. He's supposed to patrol the outside of a warehouse that's 600 feet long and 400 feet wide. If Carson is supposed to circle the warehouse 10 times, but gets tired and skips 2 times, how far does he walk in one night?
A: First find the total distance Carson walks along the warehouse's long sides: 600 feet / side * 2 sides = 1200 feet. Then find the total distance Carson walks along the warehouse's short sides: 400 feet / side * 2 sides = 800 feet. Add those two amounts to find the total distance walk in one circle: 1200 feet + 800 feet = 2000 feet. Then find the number of circles Carson actually walks: 10 circles - 2 circles = 8 circles. Then multiply the distance of one circle by the number of circles Carson makes: 2000 feet / circle * 8 circles = 16000 feet. The answer is 16000.
Question: Ten more than twice the number of birds on the fence is 50. How many birds are on the fence?
Answer: Let x be the number of birds on the fence. We know that 10 + 2 * x = 50. Subtracting 10 from both sides, we get 2 * x = 50 - 10 = 40. Dividing both sides by 2, we get x = 20. The answer is 20.
