[Question]There are 381 pages in Elliot’s book. He has already read 149 pages. If he reads 20 pages a day for a week, how many pages are still left to be read?
[Answer]In a week, Elliot will read 20 x 7 = 140 pages. Adding the prior readings, he has read a total of 149 + 140 = 289 pages. There are 381 - 289 = 92 pages still left to be read. The answer is 92.
Q: A family has three adults and children, both girls and boys. They went out for a family trip and prepared 3 dozen boiled eggs for the trip. Every adult got 3 eggs, and the boys each received 1 more egg than each girl since the girls had some snacks. How many boys went on the trip if the number of girls was 7 and each girl received an egg?
A: The total number of eggs the family had is 3 * 12 = 36 eggs. If each adult received 3 eggs, the total number of eggs they got is 3 * 3 = 9 eggs. The children shared 36 - 9 = 27 eggs. Since each girl received an egg, the boys shared 27 - 7 = 20 eggs. If each boy received 1 egg more than each girl, each received 1 + 1 = 2 eggs. The boys received 20 eggs, and if each got 2 eggs, then 20 / 2 = 10 boys went on the trip. The answer is 10.
Question: Kameron has 100 kangaroos on his large farm; Bert has 20 kangaroos on his farm. In how many more days will Bert have the same number of kangaroos as Kameron does now if he buys kangaroos at the same rate of 2 new kangaroos per day?
Answer: If Kameron has 100 kangaroos, he has 100 - 20 = 80 more kangaroos than Bert. Buying 2 kangaroos every day, it will take Bert 80 / 2 = 40 days to have the same number of kangaroos as Kameron has now. The answer is 40.
[Question]Natalia is riding a bicycle for the cycling competition. On Monday she rode 40 kilometers and on Tuesday 50 kilometers. On Wednesday she rode 50% fewer kilometers than the day before. On Thursday she rode as many as the sum of the kilometers from Monday and Wednesday. How many kilometers did Natalie ride in total?
[Answer]On Wednesday she covered half of the distance from Tuesday, so 50 / 2 = 25 kilometers. On Thursday she rode 40 + 25 = 65 kilometers. In total, Natalia rode 40 + 50 + 25 + 65 = 180 kilometers. The answer is 180.
Q: Saheed made four times as much money as Kayla. Kayla made $30 less than Vika. Vika made $84. How many dollars did Saheed make?

Question: A special school for deaf and blind students has a deaf student population three times the size of blind student population. If the number of deaf students is 180, how many students are there altogether?
Answer:
Call the number of blind students b. There are 180 deaf students, which is three times the number of blind students, so 3b = 180. Multiplying both sides of the equation by 1 / 3 gives b = (1 / 3) * 180 = 60. The total number of students is 180 + 60 = 240. The answer is 240.
