x is 4

Step 2: add 19 to both sides
20x -19+19=61+19

Answer: the 20 fluid ounces is better
Step-by-step explanation:

You want to divide 20 by 4.40 because 20 is the fluid ounces and 4.40 is the money divide that to get the cost per fluid ounce then you do the same with the 24 fluid ounces and by doing that you get the sot for 1 fluid ounce then look at both of your answers and see which one is less. which one is less is the better one.
