peaches are being sold for $2 per pound. the customer created a model to represent the total cost of peaches bought. if $x$ represents the number of pounds of peaches bought and $y$ represents the total cost of the peaches, which best describes the values of $x$ and $y$?\nthe values of both $x$ and $y$ can be any real number.\nthe values of both $x$ and $y$ will be real numbers greater than or equal to 0.\nthe value of $x$ and $y$ will always be zero\nthe value of $x$ can be any real number greater than or equal to 0, but the value of $y$ must be an integer greater than or equal to 0.
Answer
Explanation:
Step1: Analyze the meaning of variables
$x$ is the number of pounds of peaches bought and $y$ is the total cost. You can't buy a negative - amount of peaches, so $x\geq0$. Also, the cost $y$ can't be negative since it's based on a non - negative quantity of peaches and a positive price per pound.
Step2: Consider the nature of the values
The number of pounds of peaches $x$ can be a non - negative real number (you could buy, for example, 0.5 pounds). The total cost $y = 2x$. Since $x\geq0$ and the price per pound is $2$, then $y = 2x\geq0$ and $y$ is also a non - negative real number.
Answer:
The values of both $x$ and $y$ will be real numbers greater than or equal to 0.
