Rene can finish reading 30 pages in 60 minutes. Lulu can read 27 pages in 60 minutes and Cherry can read 25 pages in 60 minutes. If they have been reading for 240 minutes now, how many pages have they finished reading in total? Give the rationale and then the answer.
Let's think step by step. Rene finished 30 x 4 = 120 pages in 240 minutes. Lulu finished 27 x 4 = 108 pages in 240 minutes. Cherry finished 25 x 4 = 100 pages in 240 minutes. Therefore they have finished a total of 120 + 108 + 100 = 328 pages in 240 minutes.. The answer is: 328.

Tim has 30 toads. Jim has 20 more toads than Tim does. Sarah has twice as many toads as Jim does. How many toads does Sarah have? Give the rationale and then the answer.
Let's think step by step. Jim has 30 + 20 = 50 toads. Sarah has 50 * 2 = 100 toads.. The answer is: 100.

Andrea buys herself a pony for her 30th birthday. She pays $500/month to rent a pasture for it, $10 a day for food, and $60/lesson for two lessons a week. How much does she spend on her pony in a year? Give the rationale and then the answer.
Let's think step by step. First find the annual cost of food: $10 / day * 365 days = $3650. Then find how much she spends a week on lessons: $60 / lesson * 2 lessons = $120. Then multiply that weekly cost by the number of weeks per year to find the annual cost: $120 / week * 52 weeks / year = $6240. Then find the annual cost of the pasture: $500 / month * 12 months / year = $6000. Then add all the costs to find the total cost: $6000 + $6240 + $3650 = $15890.. The answer is: 15890.
