Answer

Answer:

The value of x can be any integer greater than or equal to 0, and y will be an integer greater than or equal to 0.

Explanation:

Step1: Analyze x - number of notebooks

You can't buy a fraction of a notebook. So the number of notebooks (x) must be a non - negative integer (0, 1, 2, 3,...).

Step2: Analyze y - total cost

Since (y = 3x) (cost per notebook is $3), and (x) is a non - negative integer, then (y) (the total cost) will also be a non - negative integer. For example, if (x = 0), (y=3\times0 = 0); if (x = 1), (y = 3\times1=3); if (x = 2), (y=3\times2 = 6) and so on.
