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.
