Answer
Attempt 1 out of 2
Equation:
Answer: xx =
Let x be the cost of each bottle of juice.
The cost of the 12-pack of juice bottles would be 12x.
The total cost before tax was $15.78, so we can set up the equation:
$2.70 + 12x = $15.78
Now we can solve for x:
12x = $15.78 - $2.70
12x = $13.08
x = $13.08 / 12
x = $1.09
Therefore, each bottle of juice cost $1.09.
