Answer:
$1.34
Step-by-step explanation:
He bought a bag of popcorn for $1.68 and a 15-pack of juice bottles.
The total cost before tax was $21.78.
Let the number of juice bottles = x
Hence, our Equation is given as:
$1.68 + 15 × x = $21.78
$1.68 + 15x = $21.78
Collect like terms
15x = $21.78 - $1.68
15x = $20.1
x = $20.1/15
x = $1.34
Therefore, the cost for each bottle of juice = $1.34
