[Question]Bubba bought a new two-story warehouse. When empty, the first floor of the building contains twice as much floor space for storage as the second floor. The first items he brought into his empty building were several thousand boxes; and he put them all on the second floor, which filled one-quarter of the second floor storage space. If the boxes used up 5,000 square feet of storage space, how many square feet of storage space is still available in the building?
[Answer]If 5,000 square feet represents one - quarter of the second floor storage space, then the second floor has 5,000 * 4 = 20,000 square feet of storage space. Since the first floor has twice as much space as the second floor, then the first floor has 20,000 * 2 = 40,000 square feet of storage space. Altogether, when empty, the entire building has 20,000 + 40,000 = 60,000 square feet of storage space. Since the second floor has 5,000 square feet of storage space filled with boxes, then there are 60,000 - 5,000 = 55,000 square feet of unused storage space still available in the building. The answer is 55000.
Q: A school library has 120 books. Each student needs 5 books for their classes. The library was able to help 4 students on the first day of school, 5 students on the second day and 6 students on the third day. How many students can the library help out on the fourth day of school?
A: On the first day, the library used 4 students * 5 books = 20 books. On the second day, the library used 5 students * 5 books = 25 books. On the third day, the library used 6 students * 5 books = 30 books. On the fourth day, the library had 120 books - 20 - 25 - 30 = 45 books remaining. The library can help 45 books / 5 books = 9 students on the fourth day. The answer is 9.
Question: Haleigh needs to buy leggings for her pet animals. She has 4 dogs and 3 cats. How many pairs of leggings does she need?
Answer: The dogs have 16 total legs because 4 times 4 equals 16. The cats have 12 total legs because 4 times 3 equals 12. There are 28 total legs because 16 plus 12 equals 28. She needs to buy 14 pairs because 28 divided by two equals 14. The answer is 14.
[Question]Yella's computer usage last week was 91 hours. If she plans to use the computer 8 hours a day for this week, how much less ​is her computer usage for this week?

Q: Jill bought 5 packs of red bouncy balls and 4 packs of yellow bouncy balls. Each package contained 18 bouncy balls. How many more red bouncy balls than yellow bouncy balls did Jill buy?
A: Jill bought 5 packs * 18 red balls = 90 red balls. Jill bought 4 packs * 18 yellow balls = 72 red balls. Jill had 90 red – 72 yellow = 18 more red balls. The answer is 18.
Question: If Ken's house is twice as far from Dawn's house as Mary's house along a certain road, and Ken's house is 4 miles away from Dawn's house along this same road, how much distance (in miles) will Ken cover if he goes from his house to Dawn's house, then Mary's, then back to Dawn's before going back to his own house?
Answer:
Ken's house is twice as far from Dawn's house as Mary's, so the distance between Ken's and Mary's is half that between Ken's and Dawn's (4 miles) which means the former is (1 / 2) * 4 miles = 2 miles. If Ken goes from his house to Dawn's, he has covered 4 miles. He goes from there to Mary's (2 miles, same as Ken's to Mary's) for a total of 4 + 2 = 6 miles. He goes back to Dawn's (another 2 miles) for a total of 6 + 2 = 8 miles. Then he goes to his own house (4 miles) for a final total of 8 + 4 = 12 miles. The answer is 12.
