Answer 2

Calculating the Total Number of Characters in Three Books

To calculate the total number of characters in the three books, we can use the given information about the character counts in each book.

Let's denote: - The number of characters in the first book as x. - The number of characters in the second book as y. - The number of characters in the third book as z.

Given: 1. The first book has 4573 characters. 2. The second book has 1375 characters less than the first book. 3. The third book has three times more characters than the sum of the first and second books.

We can express the relationships between the character counts in the three books as follows: 1. y = x - 1375 2. z = 3 * (x + y)

Calculating the Total Number of Characters

Let's solve for the total number of characters in the three books using the given information.

First, we can substitute the value of y from the first equation into the second equation to express z in terms of x: z = 3 * (x + (x - 1375))

Solving for z: z = 3 * (2x - 1375)

Now, we can substitute the value of z into the equation: 4573 + (4573 - 1375) + z = 3 * (2 * 4573 - 1375)

Solving for z: 4573 + 3198 + z = 3 * (9146 - 1375) 7771 + z = 3 * 7771 z = 3 * 7771 - 7771 z = 15542 - 7771 z = 7771

Answer

The total number of characters in the three books is 7771.
