The number of children is 4 and the number of notebooks is 60.

<u><em>Explanation</em></u>

Lets assume, Mama has x number of children and y number of notebooks.

If she give 13 notebooks to each of her children, then 8 books are left. So,

y=13x+8 ...............................(1)

And If she give 15 notebooks to each of her children, she will have nothing left. That means y= 15x ..............................(2)

Now solving the system of equations, we will get ....

13x+8=15x\\ \\ 13x-15x= -8\\ \\ -2x= -8\\ \\ x=\frac{-8}{-2}=4

Now, y=15x=15(4)=60

So, the number of children is 4 and the number of notebooks is 60.
