Question: Tracy has been collecting novels from her friends to donate to the Children For The Future charity organization. In the first week she collects a certain number of books. In the next five weeks, she collects ten times as many books as she did in the first week. How many books did she collect in the first week if she has 99 books now?
Answer: Let's say the number of books she had in the first week is x. After six weeks, Tracy has x + x * 10 = 99 books. Combining like terms, we get 11x = 99. Dividing both sides by 11, we find that the number of books Tracy had in the first week is x = 9. The answer is 9.
[Question]Kennedy's house is 600 square feet larger than 4 times Benedict's house. If Kennedy's house is 10000 square feet, how many square feet is Benedict's house?
[Answer]Let the number of square feet in Benedict's house be x. So, we can write the equation 4 * x + 600 = 10000. Subtracting 600 from both sides we get 4 * x = 9400. Dividing both sides by 4 we get x = 2350 square feet. The answer is 2350.
Q: Erica lives near a lake where most locals sell fish as their main source of income, earning $20 per kg of fish. She goes out fishing today and catches twice as many fish as she caught in total in the past four months. If Erica trawled 80 kg of fish in the past four months, not including today, how much money will she have earned in the past four months including today (assuming she sells all her fish)?
A: In the past four months, not including today, Erica has 80 kg * $20 / kg = $1600 worth of fish. Today, Erica trawled 80 * 2 = 160 kg of fish. Thus today's earnings are 160 kg * $20 / kg = $3200. Her total earnings are $3200 + $1600 = $4800. The answer is 4800.
Question: Robert, a sales agent, earns a basic salary of $1250 per month and, 10% commission on his monthly sales. Last month, his total sales were $23600. He allocated 20% of his total earnings to savings and the rest of the money to his monthly expenses. How much were his monthly expenses last month?
Answer: Robert earned a commission of $23600 x 10 / 100 = $2360. So, he earned a total of $1250 + $2360 = $3610. And, he saved $3610 x 20 / 100 = $722. Therefore, his total expenses last month was $3610 - $722 = $2888. The answer is 2888.
[Question]Miles and Daphne are comparing their reading collection and want to figure out who has more pages. They are about to count each page, but their parents suggest that they see whose collection is taller. Mile's collection is taller, but then Daphne notices that Miles reads board books, and so the pages are thicker. After some more measuring, they figure out that for Miles, 1 inch equals 5 pages, but for Daphne 1 inch equals 50 pages. If Miles's books are 240 inches tall and Daphne's collection is 25 inches tall, how many pages are in the longest collection?
[Answer]Miles's collection has 1,200 pages because 240 x 5 = 1,200. Daphne's collection has 1,250 pages because 25 x 50 = 1,250. The largest collection has 1,250 pages because 1,250 > 1,200. The answer is 1250.
