c. the value of x can be any integer, and y will be an integer.
d. 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.

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.

Step-by-step explanation:

Cost of 1 notebook = $3

x represents the number of notebooks  

Since the number of notebooks cannot be negative .

So, x can be 0 or positive integer.

y represents the total cost of the notebooks .

Since Cost of 1 notebook is $3

So, Cost of notebooks will be in the multiples of 3.

So, y can be 0 or  positive integer.

Thus Option D is correct.

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.
