Q: Olaf is sailing across the ocean with 25 men, including himself. He needs 1/2 a gallon of water per day per man. The boat can go 200 miles per day and he needs to travel 4,000 miles. How many gallons of water does he need?
A: He needs 12.5 gallons per day because 25 x .5 = 12.5. It will take 20 days of travel because 4,000 / 200 = 20. He will need 250 gallons of water because 20 x 12.5 = 250. The answer is 250.
Question: Chris buys 2 and a half dozen donuts on his way to work to share with his co-workers. While driving, he eats 10% of the donuts. Once inside, he grabs another 4 donuts for his afternoon snack. How many donuts are left for his co-workers?
Answer: He buys 2 and a half dozen donuts so that's 2.5 * 12 = 30 donuts. He eats 10% of the donuts on his way to work so he eats .10 * 30 = 3 donuts. He bought 30 donuts and ate 3 so that leaves 30 - 3 = 27 donuts. Once inside, he grabs another 4 donuts of his afternoon snack so that leaves 27 - 4 = 23 donuts for his co - workers. The answer is 23.

Q: There were 600 people in the stadium when the football game started. Before the game was over, one-fourth of the boys and one-eighth of the girls left early. How many people remained to see the end of the game if there were 240 girls at the beginning of the game?
A:
There were 600 - 240 = 360 boys at the beginning of the game. So, 360 x 1 / 4 = 90 boys left early. And 240 x 1 / 8 = 30 girls left early. A total of 90 + 30 = 120 people left early. Therefore, 600 - 120 = 480 people remained to see the end of the game. The answer is 480.
