There are chickens roaming the chicken farm. The roosters outnumber the hens 2 to 1. If there are 9,000 chickens on the chicken farm, how many roosters are there? Give the rationale and then the answer.
Let's think step by step. There are 9000 / (2 + 1) = 3000 hens on the farm. There are 3000 * 2 = 6000 roosters on the farm.. The answer is: 6000.

Last week, the price of a movie ticket was $100. This year the price is down by 20%. What's the new price of the movie ticket? Give the rationale and then the answer.
Let's think step by step. The price of the book is down by: 100 * 0.2 = $20. So the new price of the movie ticket is: 100 - 20 = $80.. The answer is: 80.

Lance has 70 cents, Margaret has three-fourths of a dollar, Guy has two quarters and a dime, and Bill has six dimes. How many cents do they have combined? Give the rationale and then the answer.
Let's think step by step. Margaret has 100 * 0.75 = $0.75. Guy has $0.25 + $0.25 + $0.10 = $0.60. Bill has 6 * $0.10 = $0.60. Lance, Margaret, Guy and Bill have $0.70 + $0.75 + $0.60 + $0.60 = $2.65. Thus they have $2.65 * 100 = 265 cents.. The answer is: 265.
