[Question]Vicente saw Sophie's mom giving Sophie 20 oranges every day to carry to school to eat. He also saw Hannah's dad giving Hannah 40 grapes every day to eat at the school. If he counted the number of fruits that the girls were given for 30 days, calculate the total number of fruits that Sophie and Hannah had eaten in the 30 days.
[Answer]If Sophie was given 20 oranges every day for thirty days, she had taken 20 * 30 = 600 oranges to school. Similarly, in the thirty days, Hannah had taken 40 * 30 = 1200 grapes to school. In the thirty days, Hannah and Sophie took 1200 + 600 = 1800 fruits to school. The answer is 1800.
Q: In the spelling bee, Max has 5 points, Dulce has 3 points, and Val has twice the combined points of Max and Dulce. If they are on the same team and their opponents' team has a total of 40 points, how many points are their team behind?
A: Max and Dulce's total combined points are 5 + 3 = 8. So, Val got 8 x 2 = 16 points. And the total points of their team is 8 + 16 = 24. Therefore, their team is 40 - 24 = 16 points behind. The answer is 16.
Question: Biff is getting ready for a long bus trip. He spends $11 on the ticket, $3 on drinks and snacks, and $16 on a new pair of headphones to listen to music. Biff plans to do online tasks using the bus's WiFi during his trip. If Biff makes $12/hour working online and has to pay $2/hour to access the bus's WiFi, how many hours long will the bus ride need to be for him to break even?
Answer: First calculate how much money Biff spent getting ready for the trip: $11 + $3 + $16 = $30. Now calculate Bill's net income per hour after he pays for WiFi by subtracting the WiFi cost from his gross hourly rate: $12 / hr - $2 / hr = $10 / hr. Finally, divide the money Bill spent by his net hourly rate to find out how many hours he has to work to break even: $30 / $10 / hr = 3 hours. The answer is 3.
[Question]James decides to cut down some trees. In the first 2 days, he cuts down 20 trees each day. For the next 3 days his 2 brothers help him cut down trees. They cut 20% fewer trees per day than James. How many total trees were cut down?
[Answer]He cuts down 2 * 20 = 40 trees by himself. Each of his brothers cuts down 20 * .2 = 4 fewer trees per day. So they each cut down 20 - 4 = 16 trees. So for the next 3 days they cut down 20 + 16 * 2 = 52 trees per day. So they cut down 40 + 52 * 3 = 196 trees. The answer is 196.
Q: Bill the miner discovers a vein of fool's gold. He successfully sells 8 ounces to a merchant, but when he tries to sell to the sheriff he's arrested, fined $50 and run out of town on a rail. If Bill earned $9 for every ounce of fool's gold he sold, how much money is he left with?
A: First find the total amount of money Bill made from the merchant: 8 ounces * $9 / ounce = $72. Then subtract the fine to find how much money he was left with: $72 - $50 = $22. The answer is 22.
Question: In one hour, Addison mountain's temperature will decrease to 3/4 of its temperature. If the current temperature of the mountain is 84 degrees, what will the temperature decrease by?
Answer:
In one hour, Addison mountain's temperature will decrease to 3 / 4 of the temperature it is now, meaning the temperature will decrease to 3 / 4 * 84 = 63 degrees. The temperature decrease will be 84 - 63 = 21 degrees. The answer is 21.
