The pet shop grooms dogs. It takes 30 minutes to groom a poodle. It takes half as much time to groom a terrier as it takes to groom a poodle. They do not groom cats. If the pet shop grooms 3 poodles and 8 terriers, what is the total length of time it will take, in minutes? Give the rationale and then the answer.
Let's think step by step. At a rate of 30 minutes per poodle, 3 poodles will take 3 * 30 = 90 minutes. If it takes half as much time to groom a terrier as it takes to groom a poodle, it takes 30 / 2 = 15 minutes per terrier. At a rate of 15 minutes per terrier, 8 terriers will take 120 minutes. Thus, in total, it will take the pet shop 90 + 120 = 210 minutes to groom 3 poodles and 8 terriers.. The answer is: 210.

Bill started reading a book on the first day of April. He read 8 pages every day and by the 12th of April, he had covered two-thirds of the book. How many pages does the book have? Give the rationale and then the answer.
Let's think step by step. He read 8 pages every day for 12 days for a total of 8 * 12 = 96 pages. 96 pages is the same as two - thirds of the total number of pages which means: number of pages * (2 / 3) = 96. Therefore the total number of pages is 96 * (3 / 2) = 144 pages.. The answer is: 144.

At the beginning of the day there were 74 apples in a basket. If Ricki removes 14 apples and Samson removes twice as many as Ricki. How many apples are left in the basket by the end of the day? Give the rationale and then the answer.
Let's think step by step. There are 74 - 14 = 60 apples left after Ricki removes some. Samson removes 14 * 2 = 28 apples. There are 60 - 28 = 32 apples left after Samson removes some.. The answer is: 32.
