Question: Ezekiel hikes as a hobby. This past summer, he did a challenging three-day hike across 50 kilometers of wilderness. The first day, he covered 10 kilometers of steep mountainside. The second day was flatter and he was able to cover half the full hike distance. How many kilometers did he have to hike on the third day to finish the hike?
Answer: After the first day, Ezekiel had 50 - 10 = 40 kilometers of the hike left. On the second day, he covered 50 / 2 = 25 kilometers. Therefore, on the third day, he had 40 - 25 = 15 kilometers left to finish the hike. The answer is 15.

Question: Stoney Hollow Middle School is taking a field trip to the zoo. There are 109 fifth graders, 115 sixth graders, and 118 seventh graders. There are 4 teachers and 2 parents from each grade coming along to chaperone on the trip. There are 72 seats on each school bus. How many buses are needed for the field trip?
Answer: There are 109 fifth graders + 115 sixth graders + 118 seventh graders = 342 students going on the trip. There are 4 teachers + 2 parents = 6 adults going on the field trip for each grade. There are 3 grades going, so 3 grades x 6 adults / grade = 18 total adults going on the trip. There are 342 students + 18 adults = 360 people going on the trip. So, 360 people / 72 seats = 5 buses. The answer is 5.

[Question]John decides to fix a racecar. It cost $20,000 to fix but he gets a 20% discount. He wins his first race but only keeps 90% of the money. The prize is $70,000. How much money did he make from the car?
[Answer]
He gets a 20000 * .2 = $4000 discount. So he paid 20000 - 4000 = $16000. He kept 70000 * .9 = $63000. So he made 63,000 - 16,000 = $47,000. The answer is 47000.
