Question 11 • GA-Algebra: Concepts and Connections CR
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?
Answer
A
The values of both x and y can be any real number.
B
The values of both x and y will be real numbers greater than or equal to 0.
C
The value of x and y will always be zero
D
The 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.
Explanation
The cost is modeled by y = 2x, where x is the number of pounds and y is the cost in dollars. Both quantities can be zero or positive, and they may include fractions or decimals—for example, 1.5 pounds costs $3. Choice B correctly says both values are real numbers greater than or equal to 0.
