Choice A is the correct answer.
We can compare the prices by taking one of the weight values from the table for apple B and plug it into the equation for apple A.
For example, let's take 4 from the table. The equation would look like this:
y = 0.85(4) = $3.40.
This is the price of 4 pounds of apple A. However, the price for 4 pounds of apple B is $5.00.
5.00 - 3.40 = $1.60. This is the difference in price between 4 pounds of apple A and 4 pounds of apple B. If we want to find the difference per 1 pound, just divide 1.60 by 4.
1.60 / 4 = $0.40.
Therefore, the answer is Choice A.
