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.

Alexandra bought 8 magazines at the bookstore on Friday. On Saturday, she went back and bought 12 more. Sunday morning, she saw that the store was having a sale and she bought four times the number of magazines she did on Friday. Later that day she discovered that her dog had chewed up 4 of the magazines. How many magazines does she have now? Give the rationale and then the answer.
Let's think step by step. By adding Friday and Saturday, Alexandra bought 12 + 8 = 20 magazines. On Sunday she buys 8 * 4 = 32 magazines. Before her dog got to them she had 12 + 8 + 32 = 52 magazines. After her dog chewed up some she had 52 - 4 = 48 magazines.. The answer is: 48.
