Answer

Part 1:  

Total number of liters of orange juice = 0.8x

Total number of liters of water = 0.2x

Part 2: The variable x represent the amount of full capacity of the container.


Explanation

Let x be the volume of the container.

Total number of orange juice = 80% of x

                                                 = 80/100 × x

                                                  = 0.8 × x

                                                 = 0.8x liters

If 80% of the container has orange juice the water will be =(100 - 80)%

                                                                                                 = 20%

The total number of liters of water = 20% of x

                                                           = 20/100 × x

                                                            = 0.2 × x

                                                           = 0.2x liters.

X ⇒The variable represent the total volume of the container. That is the full capacity of the container.
