a store sells notebooks for $3 each and does not charge sales tax. if x represents the number of notebooks adele buys and y represents the total cost of the notebooks she buys, which best describes the values of x and y? the value of x can be any real number, and y will be a real number. the value of x can be any real number greater than or equal to 0, and y will be a real number greater than or equal to 0. the value of x can be any integer, and y will be an integer. 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.

a store sells notebooks for $3 each and does not charge sales tax. if x represents the number of notebooks adele buys and y represents the total cost of the notebooks she buys, which best describes the values of x and y? the value of x can be any real number, and y will be a real number. the value of x can be any real number greater than or equal to 0, and y will be a real number greater than or equal to 0. the value of x can be any integer, and y will be an integer. 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.

Answer

Explanation:

Step1: Analyze the nature of x

The number of notebooks Adele buys, x, cannot be a negative number or a non - whole number (you can't buy a fraction of a notebook in this context). So x must be an integer greater than or equal to 0.

Step2: Analyze the nature of y

The total cost y is calculated as y = 3x (since each notebook costs $3). Since x is an integer greater than or equal to 0, y = 3x will also be an integer greater than or equal to 0.

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.
