Question: Betty has 20 books, and her sister has 1/4 times more books than Betty. What's the total number of books the two have?
Answer: Betty's sister has 1 / 4 * 20 books = 5 more books. The total number of books Betty's sister has is 20 books + 5 books = 25 books. The total number of books the two have is 25 books + 20 books = 45 books. The answer is 45.

Question: Jason is tired of the neighborhood animals raiding his trash. He pepper-sprays some raccoons and 6 times as many squirrels. If he pepper-sprays 84 animals total, how many raccoons does he pepper-spray?
Answer: Let r be the number of raccoons Jason pepper - sprays and s be the number of squirrels. We know that r + s = 84 and s = 6r. Substituting the second equation into the first equation, we get r + 6r = 84. Combining like terms, we get 7r = 84. Dividing both sides by 7, we get r = 12. The answer is 12.

Question: If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?
Answer: Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones. The answer is 111.

Question: Ben will receive a bonus of $1496. He chooses to allocate this amount as follows: 1/22 for the kitchen, 1/4 for holidays and 1/8 for Christmas gifts for his 3 children. How much money will he still have left after these expenses?
Answer:
Ben's spending for the kitchen is $1496 x 1 / 22 = $68. Ben's spending for holidays is $1496 x 1 / 4 = $374. Ben's spending for children's gifts is $1496 x 1 / 8 = $187. The total amount spent is $68 + $374 + $187 = $629. So, Ben still has $1496 - $629 = $867 left. The answer is 867.
