Answer:
The answer is C. k = 2.33; he tomatoes cost $2.33 per pound.
Explanation:
In this case we have to determine the constant of proportionality of the equation. First we have to identify the variables:
Total charge or price = t
Pounds of tomatoes = p
So the constant of proportionality k is 2.33 because it determines how the total price of a certain number of tomato pounds change. FInally, to calculate the price per pound of tomatoes we have to use the equation a apply it using 1 pound of tomatoes:

So the price of one pound is $2.33.
The answer is C. k = 2.33; he tomatoes cost $2.33 per pound.
