Q: Eighty-five cans were collected. LaDonna picked up 25 cans. Prikya picked up twice as many times as many cans as LaDonna. Yoki picked up the rest of the cans. How many cans did Yoki pick up?
A: LaDonna = 25 cans. Prikya is twice as many as LaDonna = 2 * 25 = 50. Yoki picked up the rest 85 - 25 - 50 = 10. Yoki picked up 10 cans. The answer is 10.

Q: Josh and Anna were both born on August 17th, but in different years. To consolidate celebrations they also got married on August 17 when Josh turned 22. If today they're celebrating 30 years of marriage and their combined age is exactly 5 times what Josh's age was when they married, how old was Anna when they got married?
A: We know that Josh must be 30 years older than his age when they got married, therefore he is 30 + 22 = 52 years old today. If their current combined age is 5 times the age Josh was when they married (22), then their total combined age is 5 * 22 = 110 years. That means that Anna must be 110 - 52 = 58 years old today. If they married 30 years ago, Anna must have been 58 - 30 = 28 years old when they married. The answer is 28.

Q: John carves a giant marble rectangular prism 8 meters tall with a 2-meter square base. It has a density of 2700 kg per cubic meter. How much does it weigh?
