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 = (x)/(y)`

Therefore, substituting values we have:

`C = (4)/(8)`

Rewriting we have:

`C = (2)/(4)`

`C = (1)/(2)`

`C = 0.5`

Answer:

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