8x = 4. x = 4/8. x = 0.5. The unit rate for juice boxes is $0.50.
** The unit rate for the juice boxes is: **
r = 0.5 ; For this case we have that the unit cost is given by:
r = x y
Where,
y: total cost
x: amount of total juices per box
Substituting values we have:
r = 8 4
Simplifying the obtained expression, we have:
[ r = \frac{1}{2}
r = 0.5 ]
The unit rate for the juice boxes is $0.50 each. This is calculated by dividing the total cost of $4 by the number of juice boxes, which is 8. Thus, each juice box costs fifty cents.
