and a 15-pack of juice bottles. The total cost before tax was $21.78. Write and solve an

equation which can be used to determine x, how much each bottle of juice costs?

Answer 1

$1.34

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
