x is the total number of liters of orange juice and water combined. 80% of the mixture is pure orange juice which means 20% of it is water. Therefore, x 20/100 = 1 is the equation in single variable that can be used to find x. and 20/100 is 1/5 so there are 5 total liters in all and 5-1 is 4, so there are 4 liters of orange juice in the can. Hope this helps :)
Answer:
80% juice : 20% water
x : 1 liter
80 ÷ 20 = 4
1 liter x 4 = 4 liter
x = 4
Part a = x÷4 or x/4
Part b = 4 liter
