For this case we have that the unit cost is given by:

[tex] r = \frac{y}{x}
[/tex]

Where,

y: total cost

x: amount of total juices per box

Substituting values we have:

[tex] r = \frac{4}{8}
[/tex]

Simplifying the obtained expression, we have:

[tex] r = \frac{1}{2}

r = 0.5
[/tex]

Answer:

The unit rate for the juice boxes is:

[tex] r = 0.5 [/tex]
