Give the step-by-step reasoning process and then the final answer. 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?
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 final answer: 144.
