Question and rationale: The question is: Oliver has $40 and 200 quarters. If he gives his sister $5 and 120 quarters, how much money in total is he left with?
Step-by-step reasoning process: The 200 quarters equals 200 * $0.25 = $50. Oliver has a total of $40 + $50 = $90. He gives his sister 120 * $0.25 = $30 in total from the quarters. The total amount he gave to his sister is $30 + $5 = $35. Oliver is left with $90 - $35 = $55.

Question and rationale: The question is: Steve writes a letter every 3rd day to his friend. He spends 20 minutes writing the letters. It takes 10 minutes to write 1 page. He also writes a long letter at the end of the month which he puts more thought into. It takes twice as long per page but he spends 80 minutes writing. How many pages does he write a month?
Step-by-step reasoning process: He writes 30 / 3 = 10 normal letters. Each letter is 20 / 10 = 2 pages. So that is 2 * 10 = 20 pages. His long letter takes 2 * 10 = 20 minutes per page. So it is 80 / 20 = 4 pages. So he writes 20 + 4 = 24 pages.

Question and rationale:
The question is: A gift shop sells bracelets at $15 each, a gold heart necklace at $10, and a personalized coffee mug at $20. Raine buys three bracelets, two gold heart necklaces, and one coffee mug for her friends. How much change does Raine get back if she gives a one hundred dollar bill?
Step-by-step reasoning process: Three bracelets cost 3 x $15 = $45. Two gold necklaces cost 2 x $10 = $20. Thus, the total amount is $45 + $20 + $20 = $85. Therefore, Raine gets a change of $100 - $85 = $15.
