Question: James is sitting outside, counting how many people go past him in vehicles. He has counted 52 vehicles so far today. He saw 12 trucks, a couple of buses, twice as many taxis, some motorbikes, and 30 cars. If the trucks held 2 people each, the buses held 15 people each, the taxis held 2 people each, the motorbikes held 1 person each, and the cars held 3 people each, how many passengers has James seen today?
Answer: In the trucks, James saw 12 * 2 = 24 people. In the buses, he saw 2 * 15 = 30 people. He saw 2 * 2 = 4 taxis go past him. Therefore, he saw 4 * 2 = 8 people in the taxis. In the cars, he saw 30 * 3 = 90 people. Since we know how many vehicles James saw in total, we know that he saw 52 – 12 – 2 – 4 – 30 = 4 motorbikes. So, he saw 4 * 1 = 4 people on motorbikes. He has therefore seen a total of 24 + 30 + 8 + 90 + 4 = 156 people. The answer is 156.
[Question]The bowl of fruit contains apples, pears, and bananas. There are two more pears than apples, and three more bananas than pears. If the bowl contains 19 pieces of fruit, how many bananas does it contain?
[Answer]Let A be the number of apples. There are A + 2 pears. There are (A + 2) + 3 pears. Then A + (A + 2) + ((A + 2) + 3) = 19. 3A + 7 = 19. 3A = 12. A = 4. There are 4 apples. There are (4 + 2) + 3 = 9 bananas. The answer is 9.
Q: Harly's animal shelter has 80 dogs. She adopts out 40% of them but then has to take back 5 because of personality conflicts with other dogs in their adopted homes. How many dogs does she have now?
A: First find how many dogs are adopted out: 80 dogs * 40% = 32 dogs. Then subtract the number of dogs adopted out from the total number of dogs and add the number who were returned to find the final number of dogs: 80 dogs - 32 dogs + 5 dogs = 53 dogs. The answer is 53.
Question: There's a sale at your favorite "Any item $10" retailer. If you buy 1 shirt you pay $10. If you buy 2, you get the second one at a 50% discount. If you buy 3, you get the third one at a 60% discount. How much money did you save if you bought 3 shirts?
Answer: The first shirt has no (0%) discount off the regular price ($10), therefore your discount is = 0% * $10 = $0. The second shirt has a 50% discount off the regular price ($10), therefore your discount is = 50% * $10 = $5. The third shirt has a 60% discount of the regular price ($10), therefore your discount is = 60% * $10 = $6. Therefore in total, you save $0 on the first shirt, $5 on the second one and $6 on the third one = 0 + 5 + 6 = $11. The answer is 11.
[Question]The class has to guess how many jellybeans are in a jar the teacher brought in. He lets 4 students make their guesses. The first thinks it contains 100 jellybeans. The second says there are 8 times as many. The third guesses 200 less than the third. The fourth takes the average of the first three guesses, and then adds 25 to it. How many jellybeans did the fourth student guess?
[Answer]The second student guessed 800 because 8 x 100 = 800. The third guessed 600 because 800 - 200 = 600. The total guesses of the first three is 1500 because 100 + 800 + 600 = 1500. The average of the first three guesses is 500 because 1500 / 3 = 500. The fourth student guessed 525 because 500 + 25 = 525. The answer is 525.
