Answer 2

Problem Statement

You have two boxes with a total of 126 books. One of the boxes contains 2.5 times more books than the other. You want to know how many books are in each box.

Solution

Let's denote the number of books in the first box as x and the number of books in the second box as y. We are given the following information: 1. The total number of books is 126: x + y = 126 2. The first box contains 2.5 times more books than the second box: x = 2.5y

Solving the Equations

We can solve this system of equations to find the values of x and y.

First, we can express x in terms of y using the second piece of information: x = 2.5y

Then, we can substitute this expression for x into the first equation: 2.5y + y = 126

Solving for y: 3.5y = 126 y = 126 / 3.5 y = 36

Now that we have the value of y, we can find the value of x using the equation x = 2.5y: x = 2.5 * 36 x = 90

Answer

So, there are 90 books in the first box and 36 books in the second box.
