It will stay the same.

$\frac{2(4)}{4} = 2$
$\frac{2(3)}{3} = 2$
$\frac{2(2)}{2} = 2$
$\frac{2(1)}{1} = 2$
No matter what you multiply 2 by, dividing it by the same number cancels it out, always leaving you with 2.

Cindy plans to shop for her school supplies and wants to know how much money she would need to spend. from her friend she knows

Let the cost of 1 notebook be x and the cost of 1 binder be y.

4 notebooks and 3 binders would cost 23.5

Therefore, 4x + 3y = 23.5 (1)

7 notebooks and 6 binders would cost 44.5

Therefore, 7x + 6y = 44.5 (2)

Multiply the first equation by 2.

8x + 6y = 47 (3)

(3) - (2) gives

x = 2.5

Substitute the value of x in (1), we get,

4(2.5) + 3y = 23.5

10 + 3y = 23.5

3y = 23.5 - 10

3y = 13.5

y = 13.5/3

y = 4.5

Hence, cost of 5 notebooks and 3 binders is:

5x + 3y = 5(2.5) + 3(4.5)

= 12.5 + 13.5

= 26

Hence, cost of 5 notebooks and 3 binders is $26.
