[Question]Julio has four bottles of orange soda and seven bottles of grape soda in his fridge. His friend Mateo has a bottle of orange soda and 3 bottles of grape soda in his fridge. If the amount of beverage in each bottle is 2 liters, how many more liters of soda does Julio have?
[Answer]Julio has 4 * 2 = 8 liters of orange soda. Julio also has 7 * 2 = 14 liters of grape soda. Julio therefore has a total of 8 + 14 = 22 liters of soda. The amount of orange soda that Mateo has is 1 * 2 = 2 liters of orange soda. In addition, Mateo has 3 * 2 = 6 liters of grape soda. In total, Mateo has 2 + 6 = 8 liters of soda. This means that Julio has 22 - 8 = 14 liters more of soda. The answer is 14.
Q: Alex is stacking his books in a pyramid. Each level of the pyramid has 80% as many books as the number of books in the previous level. If he makes four levels and the top level has 64 books, how many books are in the pyramid in total?
A: The third level has 80 books because 64 / .8 = 80. The second level has 100 books because 80 / .8 = 100. The first level has 125 books because 100 / .8 = 125. In total there are 369 books because 64 + 80 + 100 + 125 = 369. The answer is 369.
Question: In one of the teacher's meetings, it was agreed that each class will contribute $90 for a school activity.

If the remaining amount will be divided among 19 students, how much will each student contribute?
Answer: The 19 students will divide equally the remaining $90 - $14 = $76. So, each student will contribute $76 / 19 students = $4 / student. The answer is 4.

Q: An archaeologist discovered three dig sites from different periods in one area. The archaeologist dated the first dig site as 352 years more recent than the second dig site. The third dig site was dated 3700 years older than the first dig site. The fourth dig site was twice as old as the third dig site. The archaeologist studied the fourth dig site's relics and gave the site a date of 8400 BC. What year did the archaeologist date the second dig site?
A: The third dig site was dated from the year 8400 / 2 = 4200 BC. Thus, the first dig site was dated from the year 4200 - 3700 = 500 BC. The second dig site was 352 years older, so it was dated from the year 500 + 352 = 852 BC. The answer is 852.
Question: The Franzia wine is three times as old as the Carlo Rosi, while the Carlo Rosi is four times older than the Twin Valley. Calculate the total age of the three brands of wine if the Carlo Rosi is 40 years old.
Answer:
If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3 * 40 = 120 years old. The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120 + 40 = 160 years. The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40 / 4 = 10 years old. Together, the three bands have a total of 10 + 160 = 170 years of existence. The answer is 170.
