Answer 1

The constant of proportionality is 2

The equation is y=2x

Explanation:

The unit price or unit rate is $2

Let y represent the price of tomatoes, then the price of x tomatoes is

`y=2x` dollars.

This represents a direct variation.

This equation is of the form
`y=kx`, where k=2 is the constant of proportionality.
