13 notepads cost $21

Answer 1

In this case, we can represent the cost of each notepad as "x" dollars.

So, the cost of 13 notepads would be 13 * x dollars.

According to the problem, the cost of 13 notepads is $21.

Therefore, we can write the equation as:

13x = 21

To find the value of x, we divide both sides of the equation by 13:

x = 21/13

Simplifying the fraction gives us:

x ≈ 1.615

So, each notepad costs approximately $1.615.
