John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now?
Let's think: He lost 500 * .8 = 400 pounds from his bench. So his bench went to 500 - 400 = 100 pounds. After training it increased to 100 * 3 = 300 pounds.. The answer is: 300.

The long jump finals contained four national champions competing against one another. The first competitor jumped a distance of 22 feet. The second competitor jumped one foot farther than the first competitor. The third competitor jumped two feet shorter than the third competitor. And the fourth competitor jumped 3 feet further than the third competitor. How long, in feet, did the fourth competitor jump?
Let's think: The second competitor jumped one foot farther than the first competitor, for a distance of 22 + 1 = 23 feet. The third competitor jumped two feet shorter than the third competitor, for a distance of 23 - 2 = 21 feet. And the fourth competitor jumped 3 feet further than the third competitor, for a distance of 21 + 3 = 24 feet.. The answer is: 24.

Jane had a 500 page book to read. The first half of the book Jane read with a speed of 10 pages per day, and the second half with a speed of 5 pages a day. How many days did Jane spend reading this book?
Let's think: Half of the book means 500 / 2 = 250 pages. Reading the first half took Jane 250 / 10 = 25 days. Reading the second half of the book took Jane 250 / 5 = 50 days. So in total Jane needed 25 + 50 = 75 days to read the whole book.. The answer is: 75.

Emma's bank account has $100 in it. Each day of the week, she spends $8. At the end of the week, she goes to the bank and asks for as many $5 bills as her account can give her. She leaves the rest in the account. How many dollars remain in the account?
Let's think:
She spend $56 because 7 x 8 = 56. She has $44 left in the bank because 100 - 56 = 44. She can get 8 five dollar bills because 44 / 5 = 8.8. This is equal to $40 because 8 x 5 = 40. She has $4 left in the account because 44 - 40 = 4.. The answer is: 4.
