Answer 2

The 14oz bottle.

Explanation:

Best approach is to find the price per ounce, so that we can compare them on equal terms.

For this, divide each of the prices by the respective volume:

`2.50 / 10 = 0.25 \\ 2.80 / 14 = 0.20 \\ 4.00 / 16 = 0.25 \\ 5.40 / 18 = 0.30`

Therefore, we see that the best deal is the 14oz one, having the lowest price per ounce.
