Question

theo's mom bought an eight -pack of juice boxes at the store for $4. find the unit rate for the juice boxes. (example 4 ) __________

Answer 1

If $4 buys 8 juice boxes, then, dividing by 8, the rate is $0.50 per juice box, or two juice boxes per dollar.

Answer 2

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.
