Answer 1

Part A: choose the variable and state what it represents:

what percentage of water is in the can?

create an equation for Part A:

solve the equation:

Part B: if the entire can holds 80% of orange juice, how many liter of orange juice are in the can?

Answer 2

let the total juice mixture= x litre
juice=x*80/100=0.8x
now in it water =mixture-juice=x-0.8x=0.2 x
but water=1 litre
x=1/0.2
