[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.
So the answer is 220.

[Question]: Daniel owns a textile company. Every Monday he delivers 20 yards of fabric, and every Tuesday he delivers twice the amount of fabric he delivers on Monday. Every Wednesday, he delivers 1/4 of the amount of fabric he delivers on Tuesday. If each yard of fabric costs $2 and each yard of yarn costs $3, how much does he earn from Monday to Wednesday?
[Answer]: Every Tuesday, Daniel delivers 20 x 2 = 40 yards of fabric. Every Wednesday, he delivers 40 x 1 / 4 = 10 yards of fabric. Thus, he delivers a total of 20 + 40 + 10 = 70 yards of fabric from Monday to Wednesday. Therefore, Daniel earns $2 x 70 = $140 from it.
So the answer is 140.

[Question]: Ian is looking to lose some weight. He decides to start jogging around his apartment complex every night to burn some calories. He does 5 laps around the complex every night. Each lap is 100 feet. If it takes 25 feet of jogging to burn a calorie, how many calories does Ian burn after 5 days of jogging like this?
[Answer]:
First, we need to determine how many feet Ian runs in a week. We begin this by multiplying the number of laps by the number of feet per lap, performing 5 * 100 = 500 feet per day. Since there are 5 days in the period being measured, this means Ian runs 500 * 5 = 2500 feet jogged. Since it takes 25 feet of jogging to burn a calorie, this means Ian burns 2500 / 25 = 100 calories burned jogging throughout the week.
So the answer is 100.
