Question

Peaches are being sold for $2 per pound. If x represent the number of pounds of peaches bought and y represent the total cost of peaches, which best describes the value of x and y

Answer 1

Explanation:

y = 2*x

or

x = 1/2*y

Answer 2

Answer with explanation:

Let the number of pounds of peaches bought be represented by = x

Let the total cost of peaches be represented by = y

Since x represents the number of pounds of peaches bought, this should be greater than or equal to 0 means it cannot be negative number.

The equation with respect to y is :
`y=2x`

As x is greater than or equal to 0, then y=2x also should be greater than or equal to 0.

This proves that x and y both can be real numbers with equation
`y=2x`
