Question: A tree had 1000 leaves before the onset of the dry season, when it sheds all its leaves. In the first week of the dry season, the tree shed 2/5 of the leaves. In the second week, it shed 40% of the remaining leaves. In the third week, the tree shed 3/4 times as many leaves as it shed on the second week. Calculate the number of leaves the tree hadn't shed by the third week.
Answer: In the first week, the tree shed 2 / 5 * 1000 = 400 leaves. The number of leaves remaining on the tree at the end of the first week is 1000 - 400 = 600. In the second week, the tree shed 40 / 100 * 600 = 240 leaves. The number of leaves remaining on the tree is 600 - 240 = 360. The third week the tree shed 3 / 4 of its leaves, a total of 3 / 4 * 360 = 270 leaves. The number of leaves remaining on the tree is 360 - 270 = 90 leaves. The answer is 90.

Q: Jordan's dog, Max, was born on the same day that Luka turned 4 years old. Luka is exactly 2 years older than is Aubrey. On Aubrey's 8th birthday, how many years old was Jordan's dog, Max?
A: If Luka is exactly 2 years older than is Aubrey, then on Aubrey's 8th birthday, Luka was 8 + 2 = 10 years old. If Jordan's dog, Max, was born on the same day that Luka turned 4 years old, then when Luka was 10 years old, Max was 10 - 4 = 6 years old. The answer is 6.
Question: Jenny and Mark are throwing bottle caps. Jenny's bottlecap flies 18 feet straight, then bounces off a street light and flies another 1/3 of the distance it already went. Mark's bottle cap flies 15 feet forward, then bounces off a window and flies twice as far as it already did. How much further did Mark's bottle cap go than Jenny's?
Answer: First find 1 / 3 of the distance Jenny's bottlecap went straight: 18 feet / 3 = 6 feet. Then add that to the distance it flew straight to find the total distance it traveled: 6 feet + 18 feet = 24 feet. Then find twice the distance Mark's bottlecap went straight: 15 feet * 2 = 30 feet. Then add that distance to the distance it flew straight to find the total distance it traveled: 30 feet + 15 feet = 45 feet. Then subtract the distance Jenny's bottlecap traveled from the distance Mark's traveled to find the difference: 45 feet - 24 feet = 21 feet. The answer is 21.

[Question]John climbs up 9 flights of stairs. Each flight is 10 feet. If each step is 18 inches, how many steps does he climb up?
[Answer]
He has to climb 9 * 10 = 90 feet. That means he needs to climb 90 * 12 = 1080 inches. That means he needs to climb 1080 / 18 = 60 stairs. The answer is 60.
