Q: Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?
A: Half the cans collected by Martha is 90 / 2 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans. The answer is 5.
Question: If there are sixty-five dolphins in the ocean, and three times that number joins in from a river which has its mouth at the ocean, calculate the total number of dolphins in the ocean.
Answer: When three times the number of dolphins in the ocean joins in from a river, the number of dolphins in the ocean increases by 3 * 65 = 195. The total number of dolphins in the ocean increases to 195 + 65 = 260. The answer is 260.
[Question]Nina loves to travel. She tries to travel at least 400 kilometers in one month outside of her home country. Every second month she does twice that distance. If she were able to keep up with her resolution, how many kilometers would she travel during 2 years?
[Answer]Every second month Nina does twice the regular distance, which means 400 * 2 = 800 kilometers. Two years is 24 months, so half of this time is 24 * 0.5 = 12 months. So in 12 months Nina does 400 * 12 = 4800 kilometers. And in the other 12 months, she does 800 * 12 = 9600 kilometers. So in two years, Nina would be able to make 4800 + 9600 = 14400 kilometers. The answer is 14400.
Q: Tom has a quarter as much money as Nataly. Nataly has three times as much money as Raquel. How much money do Tom, Raquel, and Nataly have combined if Raquel has $40?
A: If Nataly has 3 times as much money as Raquel, she has 3 * $40 = $120. Tom has 1 / 4 as much money as Nataly, so he has 1 / 4 * $120 = $30. Combined, the three have $30 + $120 + $40 = $190. The answer is 190.
Question: Yasna has two books. One book is 180 pages long, and the other book is 100 pages long. If Yasna wants to finish both of the books in two weeks, how many pages will Yasna need to read every day, if she reads an equal number of pages each day?
Answer: The total number of pages is 180 + 100 = 280 pages. The number of pages Yasna needs to read every day for two weeks is 280 / 14 = 20 pages. The answer is 20.
