Question: Roselyn gives Mara three times as many books as she gives Rebecca and remains with 60 books. If Rebecca received 40 books, how many books did Roselyn have before?
Answer: If Roselyn gave Rebecca 40 books, and Mara was given three times as many books, Mara has 3 * 40 = 120 books. Rebecca and Mara's total number of books is 120 + 40 = 160 books. If Roselyn gave Mara and Rebecca her books, which is 160, then she initially had 60 + 160 = 220 books. The answer is 220.

Question: Taro and Vlad play a video game competition together, earning 5 points for every win. After playing 30 rounds, Taro scored 4 points less than 3/5 of the total points scored. How many total points did Vlad score?
Answer:
If they played 30 rounds, the total possible points from wins are 5 * 30 = 150 points. Scoring 3 / 5 of the total possible points earns you 3 / 5 * 150 points = 90 points. If Taro scored 4 points less than 3 / 5 of the total points, he scored 90 points - 4 points = 86 points. If the total points scored in the game is 150, then Vlad scored 150 points - 86 points = 64 points. The answer is 64.
