For this case, the first thing we must do is define variables.

We have then:

x: total cost

y: total number of juices

The unit cost of each juice is:

\(C = \frac{x}{y}\)

Therefore, substituting values we have:

\(C = \frac{4}{8}\)

Rewriting we have:

\(C = \frac{2}{4}\)

\(C = \frac{1}{2}\)

\(C = 0.5\)

Answer:

The unit rate for the juice boxes is 0.5 $ / juice.
