Part A:
x - total number of liters
The equation is:
0.8 x + 1 = x
Part B:
0.8 x + 1 = x
1 = x - 0.8 x
1 = 0.2 x
x = 1 : 0.2 = 5 lit.
0.8 · 5 = 4 lit.
There are 4 liters of orange juice in the can.
Part A) An equation in one variable that can be used to find the total number of liters of orange juice and water in the can is defined as :

0.2x = 1
where x is the total number of liters of orange juice and water combined. 20% is water in the can.

Solving the equation:
0.2 X = 1
X = 1/0.2
X = 5

Part B)  If the entire can holds 80% of orange juice and 20% of water,
Using the ratio:
80 : 20
4 : 1
total is 5 liters.
Hence,
The can will contain 4 liters of orange juice and 1 liter of water.
