Question: Ruth prepared sandwiches. She ate 1 sandwich and gave 2 sandwiches to her brother. Her first cousin arrived and ate 2 sandwiches. Then her two other cousins arrived and ate 1 sandwich each. There were 3 sandwiches left. How many sandwiches did Ruth prepare?
Answer: Ruth's two cousins ate a total of 2 x 1 = 2 sandwiches. So there were 3 + 2 = 5 sandwiches left before her two cousins arrived. Before her first cousin arrived, there were 5 + 2 = 7 sandwiches. Ruth and her brother had 1 + 2 = 3 sandwiches altogether. Therefore, Ruth prepared 7 + 3 = 10 sandwiches.". The answer is 10.
[Question]Travis and his brother joined a trick-or-treat event. They collected 68 pieces of candy altogether. Each of them ate 4 pieces of candy after the event. How many pieces of candy were left?

Q: Stella and Twinkle are filling up a truck with a capacity of 6000 stone blocks at the rate of 250 blocks per hour per person. They work for four hours and are then joined by 6 other people who also work at the same rate. How many hours did filling the truck take?
A: Stella and Twinkle filled up the truck at the rate of 250 blocks per hour per person, a total of 2 * 250 = 500 blocks per hour for both. After working for four hours, Stella and Twinkle had filled 4 * 500 = 2000 blocks into the truck. The number of blocks they had to put into the truck for it to be full is 6000 - 2000 = 4000. When 6 more people joined Stella and Twinkle, a total of 2 + 6 = 8 people were filling the truck now. Working at the rate of 250 blocks per person, the eight people filled the truck with 250 * 8 = 2000 blocks in one hour. If there were 4000 blocks that still needed to be put into the truck, the 8 people took 4000 / 2000 = 2 hours to fill the truck with the blocks. The total time it took to fill up the tank is 4 + 2 = 6 hours. The answer is 6.

[Question]Andy is a lawyer who's working on two lawsuits. The first lawsuit has a 30% chance of paying out $5,000,000 upon a win and $0 if he loses it. The second lawsuit has a 50% chance of paying out $1,000,000 if Andy loses and a 50% chance of paying out $2,000,000 if he wins. Expressed as a percentage, how much more likely is it that Andy loses both lawsuits compared to winning both of them?
[Answer]First find the probability that Andy will lose the first lawsuit: 100% - 30% = 70%. Then multiply that probability by the probability he loses the second lawsuit: 70% * 50% = 35%. Then multiply the probabilities of Andy winning each lawsuit to find the probability he wins them both: 30% * 50% = 15%. Then subtract the probability Andy wins both lawsuits from the probability he loses both lawsuits to find the difference: 35% - 15% = 20%. The answer is 20.
