Question: 7 out of 40 people in a cafeteria are wearing checkered shirts. The rest of the people are wearing vertical stripes and horizontal stripes. The number of people wearing horizontal stripes is 4 times as many as the people wearing checkered shirts. How many people are wearing vertical stripes?
Answer: 40 people - 7 people = 33 people are wearing stripes. The number of people wearing horizontal stripes is 4 horizontal stripes / checkered shirt x 7 checkered shirts = 28 horizontal stripes. The number of people wearing vertical stripes is 33 total stripes - 28 horizontal stripes = 5 vertical stripes. The answer is 5.
[Question]Freddie and his team are collecting blankets for three days to be donated to the Children Shelter Organization. There are 15 people on the team. On the first day, each of them gave 2 blankets. On the second day, they tripled the number they collected on the first day by asking door-to-door. On the last day, they set up boxes at schools and got a total of 22 blankets. How many blankets did they collect for the three days for donation?
[Answer]They collected 15 x 2 = 30 blankets on the first day. Freddie and his team collected 30 x 3 = 90 blankets on the second day. They collected a total of 90 + 22 + 30 = 142 for three days. The answer is 142.
Q: In a court-mandated traffic class, there are a certain number of drunk drivers and 3 less than 7 times that many speeders. If there are 45 students total, how many drunk drivers are there?
A: Let d be the number of drunk drivers and s be the number of speeders. We know that d + s = 45 and s = 7d - 3. Substituting the second equation into the first equation, we get d + 7d - 3 = 45. Combining like terms, we get 8d - 3 = 45. Adding 4 to both sides, we get 8d = 48. Dividing both sides by 8, we get d = 6. The answer is 6.
Question: A firefighter's hose can deliver 20 gallons of water per minute. For a building fire that requires 4000 gallons of water to put out, how long will it take, in minutes, for a team of 5 firefighters, each with their own hose, to put out the fire?
Answer: A team of 5 firefighters with hoses can deliver 5 * 20 = 100 gallons of water per minute. To deliver 4000 gallons, this team will take 4000 / 100 = 40 minutes to extinguish the fire. The answer is 40.
[Question]Two boxes for carrying oranges with a capacity of 80 and 50 were filled with 3/4 and 3/5 of the way full with oranges, respectively. Calculate the total number of oranges the boxes have together.
[Answer]For the box with a capacity of 80, if it was 3 / 4 full with oranges, it had 3 / 4 * 80 = 60 oranges. The second box, with a capacity of 50, was 3 / 5 full with oranges, which totals 3 / 5 * 50 = 30 oranges. Together, the two boxes have 60 + 30 = 90 oranges. The answer is 90.
[Question]A child is making a 5-level pyramid by stacking some blocks. In the first row, he has 9 blocks. For the next rows, he has 2 less than the blocks he has from its bottom row. How many blocks did he use in all?
[Answer]
On the second row, he used 9 - 2 = 7 blocks. On the third row, he used 7 - 2 = 5 blocks. On the fourth row, he used 5 - 2 = 3 blocks. On the fifth row, he used 3 - 2 = 1 block. Therefore, he used a total of 9 + 7 + 5 + 3 + 1 = 25 blocks. The answer is 25.
