[Question]Milton has some books about zoology and 4 times as many books about botany. If he has 80 books total, how many zoology books does he have?
[Answer]Let z be the number of zoology books and b be the number of botany books. We know that z + b = 80 and b = 4z. Substituting the second equation into the first equation, we get z + 4z = 80. Combining like terms, we get 5z = 80. Dividing both sides by 5, we get z = 16. The answer is 16.
Q: John raises emu. He has 4 pens for emu and each pen has 6 emus in it. Each female emu lays 1 egg per day. If half the emu are females how many eggs does he get a week?
A: There are 6 * 4 = 24 emus. So there are 24 / 2 = 12 female emus. So he gets 12 * 7 = 84 eggs a week. The answer is 84.
Question: James started a food fight in his school's cafeteria, and the school administration is making him work off the cost of all the food he wasted at minimum wage ($8). James has to pay for 20 wasted pounds of meat at $5/pound, 15 wasted pounds of fruits and vegetables at $4/pound, 60 wasted pounds of bread products at $1.50/pound, and 10 hours of time-and-a-half pay for the janitorial staff, who normally make $10/hour. How many hours will James have to work to pay for everything?
Answer: First find the total cost of the wasted meat: $5 / pound * 20 pounds = $100. Then find the total cost of the wasted vegetables: $4 / pound * 15 pounds = $60. Then find the total cost of the wasted bread products: $1.50 / pound * 60 pounds = $90. Then find the time - and - a - half rate for the janitors: $10 / hour * 1.5 = $15 / hour. Then multiply that by the number of hours to find the total janitorial cost: $15 / hour * 10 hours = $150. Then add up all the costs to find the total cost of everything: $100 + $60 + $90 + $150 = $400. Then divide the total James owes by his hourly wage to find how many hours he needs to work: $400 / $8 / hour = 50 hours. The answer is 50.
Q: To try to get the class to eat more vegetables, the teacher says that she will start giving them good character points that the class can redeem for a movie day if they earn enough. The students need to earn 200 points to win the movie day. Each time a student eats their vegetables at lunch she gives the student 2 points. There are 25 students in the class. If they have two school weeks, otherwise known as 10 days to win the movie, what is the average number of vegetables each student must eat per school week to get a movie day?
A:
The students need eat 100 vegetables in total because 200 / 2 = 100. Each student needs to eat on average 4 vegetables because 100 / 25 = 4. Each student needs to eat 2 vegetables per school week because 4 / 2 = 2. The answer is 2.
