Question: Rex is taking lessons for his driver's license. He wants to take 40 hour-long lessons before his test, and decides to have two-hour sessions twice a week until he has done his test. After 6 weeks, how many more weeks will Rex need to continue taking lessons to reach his goal?
Answer: Each week, Rex is taking 2 hour - long lessons * 2 times a week = 4 lessons. After 6 weeks, he has done 4 lessons per week * 6 weeks = 24 lessons. So Rex still needs 40 total lessons 24 lessons taken = 16 lessons. He will therefore need lessons for another 16 lessons / 4 lessons per week = 4 weeks. The answer is 4.

Q: Austin receives $5 for every hour he helps his father build a deck in their backyard. He works for 2 hours on Mondays, an hour on Wednesdays, and 3 hours on Fridays. If Austin wants to buy a bicycle that costs $180, how many weeks does he have to work?
A: Austin works a total of 2 + 1 + 3 = 6 hours a week. Since he is paid $5 per hour of work, he'll earn $5 * 6 = 30 in a week. To make $180, he'll have to work for $180 / $30 = 6 weeks. The answer is 6.
Question: A papaya tree will grow 2 feet in the first year. In the second year, it will grow 50% more than the first year. In the third year, the tree will grow 50% more than in the second year. In the fourth year, it will grow twice as much as the third year. In the fifth year, it will grow half as much as the fourth year. When the tree is 5 years old, how tall is the tree?
Answer: In the second year, the tree will grow 2 x 1.5 = 3 feet. In the third year, it will grow 3 x 1.5 = 4.5 feet. In the fourth year, it will grow 4.5 x 2 = 9 feet. In the fifth year, it will grow 9 / 2 = 4.5 feet. When the tree is 5 years old, including the first year's growth, it will be this tall 2 + 3 + 4.5 + 9 + 4.5 = 23 feet. The answer is 23.

[Question]A company hires employees on a contract basis, depending on the availability of work. In a particular month, they hired 200 more employees on the first week than on the second week, and 150 fewer employees on the second week than on the third week. If the number of employees hired on the fourth week was twice the number hired in the third week, and the number of employees on the fourth week was 400, what's the average number of employees hired per week?
[Answer]
The fourth week had twice the number of employees as the third week, so 400 / 2 = 200 employees on the third week. In the third week, they hired 150 fewer employees than on the second week, that is 200 - 150 = 50 employees hired on the second week. The first week had 200 more hirings than the second week, that is 50 + 200 = 250 employees. The total number of employees hired is 250 + 50 + 200 + 400 = 900. The average number of employees hired per week is 900 / 4 = 225 employees. The answer is 225.
