[Question]Josiah is three times as old as Hans. Hans is 15 years old now. In three years, what is the sum of the ages of Josiah and Hans?
[Answer]Josiah is 15 x 3 = 45 years old now. In three years, Josiah will be 45 + 3 = 48 years old. Hans will be 15 + 3 = 18 years old in three years. So, the sum of their ages in three years is 48 + 18 = 66 years old. The answer is 66.
Q: Dana has 15 more pencils than Jayden, who has twice as much as Marcus. How many more pencils does Dana have than Marcus, if Jayden has 20 pencils?
A: Dana has 15 more pencils than Jayden who has 20, so Dana has 20 + 15 = 35 pencils. Jayden has 20 pencils which is twice as much as Marcus's so Marcus has 20 / 2 = 10 pencils. Dana has 35 - 10 = 25 more pencils than Marcus. The answer is 25.
Question: A van is delivering 180 bottles of drinks to a neighborhood, and each bottle contains either cider or beer or a mixture of two. Out of the 180 bottles, 40 contain only cider, 80 contain only beer, and the rest are a mixture of the two drinks. If the delivery man gives half the number of each bottle of drink to the first house, how many bottles does the first house get?
Answer: The total number of bottles containing cider or beer is 40 + 80 = 120. If the number of bottles in the van was 180, then 180 - 120 = 60 contains a mixture of the two drinks. At the first house, the delivery man dropped 1 / 2 * 40 = 20 bottles. There were also 1 / 2 * 80 = 40 bottles of beer that the delivery man gave to the first house. Together, the first house received 40 + 20 = 60 bottles of cider and beer. The total number of bottles that had a mixture of the two drinks that were dropped at the first house is 1 / 2 * 60 = 30. The first house got 60 + 30 = 90 bottles of all types of drinks. The answer is 90.
[Question]John is twice as old as Mary and half as old as Tonya. If Tanya is 60, what is their average age?
[Answer]John is 30 because 60 / 2 = 30. Mary is fifteen because 30 / 2 = 15. Their total age is 105 because 60 + 30 + 15 = 105. Their average age is 35 because 105 / 3 = 35. The answer is 35.
Q: Jason waits on a customer whose check comes to $15.00. Jason's state applies a 20% tax to restaurant sales. If the customer gives Jason a $20 bill and tells him to keep the change, how much is Jason's tip?
A: First calculate how much the tax is by multiplying $15.00 by 20%: $15.00 * .2 = $3.00. Then subtract the cost of the meal and the tax from $20 to find Jason's tip: $20 - $15.00 - $3.00 = $2.00. The answer is 2.
Question: Elsa gets 500 MB of cell phone data each month. If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?
Answer:
First subtract the 300 MB Elsa spent on YouTube: 500 MB - 300 MB = 200 MB. Then multiply 200 MB by 2 / 5th to find out how much data Elsa spent on Facebook: 200 MB * 2 / 5 = 80 MB. Finally, subtract the data Elsa spent on Facebook from the 200 MB: 200 MB - 80 MB = 120 MB. The answer is 120.
