Q: Pima invested $400 in Ethereum. In the first week, it gained 25% in value. In the second week, it gained an additional 50% on top of the previous gain. How much is her investment worth now?
A: For the first week, her investment gain is $400 * 25% = $100. This leaves her investment with a value of $400 + $100 = $500. For the second week, her investment increased by $500 * 50% = $250. Pima's investment in Ethereum is now worth a total of $500 + $250 = $750. The answer is 750.
Question: Cilia wants to buy a multi-level dumbbell system. The first pair of dumbbells are 3 lb weights, the second pair is 5 lb weights and the third is 8 lb pounds. How much does the entire system weigh?
Answer: The first pair of weights weighs 3 lb each so all total they weigh 2 * 3 = 6 lbs. The second pair of weights weigh 5 lbs each so they weigh 2 * 5 = 10 lbs. The third pair of weights weigh 8 lbs each so they weigh 2 * 8 = 16lbs. All total, the entire system of weights weigh 6 + 10 + 16 = 32 lbs. The answer is 32.
[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.
Q: A child is making a 5-level pyramid by stacking some blocks. In the first row, he has 9 blocks. For the next rows, he has 2 less than the blocks he has from its bottom row. How many blocks did he use in all?
A: On the second row, he used 9 - 2 = 7 blocks. On the third row, he used 7 - 2 = 5 blocks. On the fourth row, he used 5 - 2 = 3 blocks. On the fifth row, he used 3 - 2 = 1 block. Therefore, he used a total of 9 + 7 + 5 + 3 + 1 = 25 blocks. The answer is 25.
Question: Going into the final game, Duke is so close to breaking the school's record for most points scored in a basketball season. He only needs 17 more points to tie the record. By the end of the game, Duke breaks the record by 5 points. The old record was 257 points. In the final game Duke made 5 free throws (worth one point), and 4 regular baskets (worth two points), and some three-pointers. Normally, he scores 2 three-pointers a game. How many more three-pointers did he score in the final game compared to his normal amount?
Answer: Duke scored 22 points in the final game because 17 + 5 = 22. He scored 5 points of free - throws, because 5 x 1 = 5. He scored 8 points of regular baskets because 4 x 2 = 8. He made 9 points of three - pointers because 22 - 5 - 8 = 9. He scored 3 three - pointers in the final game because 9 / 3 = 3. Duke scored 1 more than normal because 3 - 2 = 1. The answer is 1.
Q: Janine read 5 books last month. This month, she read twice as many books. If each book has 10 pages, how many pages did Janine read in two months?
