Q: Out of 804 senior high school students, 75% passed their exams and so got their degree. The rest failed. How many didn't pass their exams?
A: Find the number of students who got their degree by multiplying: 804 students * 75% = 603 students. Then find the number of students who didn't pass their exams by subtracting this number from the total: 804 students - 603 students = 201 students. The answer is 201.
Question: John is budgeting for his marriage. The venue cost $10,000. It cost $500 for each guest, and John wants 50 guests while his wife wants 60% more than that. How much would the wedding cost if John's wife gets her way?
Answer: The bride wanted 50 * .6 = 30 more guests than the husband. So the bride wanted 50 + 30 = 80 guests. So the guests cost 80 * $500 = $40000. So the total cost was $40000 + $10,000 = $50000. The answer is 50000.
[Question]Gavin has had 4 dreams every day for a year now. If he had twice as many dreams last year as he had this year, calculate the total number of dreams he's had in the two years.
[Answer]Since a year has 365 days, if Gavin has been having 4 dreams every day for a year now, he has had 4 * 365 = 1460 dreams this year. Gavin had twice as many dreams last as he had this year, meaning he had 2 * 1460 = 2920 dreams last year. The total number of dreams he has had in the two years is 2920 + 1460 = 4380 dreams. The answer is 4380.

A: 6 * 8 = 48 orange crayons. 7 * 5 = 35 blue crayons. 11 red crayons. 48 + 35 + 11 = 94. There are a total of 94 crayons. The answer is 94.
Question: A hand-crank pencil sharpener can sharpen one pencil every forty-five seconds. An electric version can sharpen one in twenty seconds. How many more pencils can the electric sharpener sharpen than the hand-crank sharpener in six minutes?
Answer: A minute is 60 seconds, so 6 minutes is 6 * 60 = 360 seconds. A hand - crank sharpener can sharpen 360 / 45 = 8 pencils in 6 minutes. An electric sharpener can sharpen 360 / 20 = 18 pencils in 6 minutes. Therefore, an electric sharpener can sharpen 18 - 8 = 10 more pencils than a hand - crank in 6 minutes. The answer is 10.
Q: A group of 6 students organized a fundraiser to go to Nicaragua for the summer. For them to go on the trip, each of them needs at least $450. On top of that, they need $3000 for their miscellaneous collective expenses. On the first day of their fundraiser, they receive $600. On the second day, they receive $900, and on the third day, they receive $400. For the next 4 days, they receive only half of what they raised on the first 3 days. How much more money does each person need to raise for them to reach their goal?
A:
All together, they need to raise ($450 x 6) + $3000 = $5700. The raised $600 + $900 + $400 = $1900 the first 3 days. For the next 4 days, they only raised $1900 / 2 = $950. In the week, they raised $1900 + $950 = $2850. They still need $5700 - $2850 = $2850. Each person still needs $2850 / 6 = $475. The answer is 475.
