The number of soldiers on opposite sides of a war each needs 10 pounds of food every day to continue fighting effectively. However, soldiers in the second are each given 2 pounds less food than the first side. If the first side has 4000 soldiers and the other side 500 soldiers fewer than the first side, what's the total amount of pounds of food both sides are eating altogether every day? Give the rationale and then the answer.
Let's think step by step. The first side with 4000 soldiers is eating 4000 * 10 = 40000 pounds of food every day. Since the other side has 500 soldiers fewer than the first side, there are 4000 - 500 = 3500 soldiers on the second side. Soldiers on the second side are each given 10 - 2 = 8 pounds of food. The total amount of food the second side eats is 8 * 3500 = 28000. Altogether, the two sides eat 28000 + 40000 = 68000 pounds of food every day.. The answer is: 68000.

Cordelia is dyeing her hair red. To get the color she wants, she first has to bleach her dark brown hair to blonde, and then she has to apply the dye. The whole process will take 9 hours. Dyeing takes twice as long as bleaching. How many hours will it take Cordelia to bleach her hair? Give the rationale and then the answer.
Let's think step by step. Let H be the number of hours it takes Cordelia to bleach her hair. A dye treatment takes twice as long, so it takes 2H. Thus, bleaching and dying will take H + 2H = 3H = 9 hours. Therefore, it will take Cordelia H = 9 / 3 = 3 hours to bleach her hair.. The answer is: 3.

There are 290 liters of oil in 24 cans. If 10 of the cans are holding 8 liters each, how much oil is each of the remaining cans holding? Give the rationale and then the answer.

Let's think step by step. 10 cans are holding 8 liters each for a total of 10 * 8 = 80 liters. There are 290 - 80 = 210 litres left. There are 24 - 10 = 14 cans left. Each of the remaining cans is holding 210 / 14 = 15 liters each.. The answer is: 15.
