Q: John decides to stop delivering the newspapers he is supposed to deliver and instead steals them to recycle them for cash. The Monday-Saturday papers weigh 8 ounces each. The Sunday paper weighs twice as much. He is supposed to deliver 250 papers a day. He doesn't deliver them for 10 weeks. If one ton of paper recycles for $20, how much did he make?
A: We know that 7 - 1 = 6 days the paper weighs 8 ounces. So those contribute 6 * 8 = 48 ounces per week. So in total a weekly delivery of papers weighs 48 + 16 = 64 ounces. That means it weighs 64 / 16 = 4 pounds. So each week he delivers 4 * 250 = 1000 pounds of paper. So in 10 weeks, he delivers 10 * 1000 = 10000 pounds of paper. That weighs 10000 / 2000 = 5 tons of paper. So he makes 5 * 20 = $100 from recycling the paper. The answer is 100.
Question: The maximum safe amount of caffeine you can consume per day is 500 mg. If each energy drink has 120 mg of caffeine and Brandy drinks 4 of them, how much more caffeine can she safely consume that day?
Answer: First find the total amount of caffeine Brandy already drank: 120 mg / drink * 4 drinks = 480 mg. Then subtract that amount from the amount it's safe to consume daily to find the remaining amount Brandy can consume: 500 mg - 480 mg = 20 mg. The answer is 20.
[Question]A case of water contains 24 bottles. A children's camp comprising of 4 groups purchased 13 cases for a 3-day camp. The first group has 14 children, the second group has 16 children, the third group has 12 children, and the fourth group has half of the number of the first three groups combined. If each child consumes 3 bottles a day, how many more bottles of water does the camp organizer still need to buy?
[Answer]The first three groups have a total of 14 + 16 + 12 = 42 children. The fourth group has 42 / 2 = 21 children. All together, the camp has 42 + 21 = 63 children. In one day, the children consume 3 x 63 = 189 bottles of water. In 3 days, the children will need 189 x 3 = 567 bottles of water. The camp organizer has already purchased 13 x 24 = 312 bottles of water. The camp organizer must buy another 567 - 312 = 255 bottles of water. The answer is 255.
Q: There are 50 children at the party. Three-fifths of them are boys. How many of the children are girls?
A: 50 x 3 / 5 = 30 children are boys. So, there are 50 - 30 = 20 children that are girls. The answer is 20.
Question: Jefferson has 56 bananas, while Walter, his friend, has 1/4 times fewer bananas. If they decide to combine their bananas and share them equally between themselves, how many bananas does Walter get?
Answer: Walter has 1 / 4 * 56 bananas = 14 fewer bananas. If Jefferson has 56 bananas, then Walter has 56 bananas - 14 bananas = 42 bananas. When they combine their bananas, they have a total of 42 bananas + 56 bananas = 98 bananas. After dividing the bananas equally, Walter gets 98 bananas / 2 = 49 bananas. The answer is 49.
Q: Mark made a chalkboard that is 3 feet wide. It is 2 times as long as it is wide. What is the area of the chalkboard?
A:
The length of the chalkboard is 2 x the width of 3 feet = 6 feet. We can calculate area by multiplying the width and the length, so 3 feet x 6 feet = 18 feet. The answer is 18.
