The equation which can be used to determine x, how much each bottle of juice cost is 9.38 = 2.21 + 3x
She bought a bag of oranges for $2.21 and a 3-pack of juice bottles.
The total cost before tax was $9.38.
Let
x = number of bottle of juice.
Hence,
The equation which can be used to determine x, how much each bottle of juice cost is as follows:
Therefore,
9.38 = 2.21 + 3x
Hence,
9.38 = 2.21 + 3x
9.38 - 2.21 = 3x
7.17 = 3x
x = 7.17 / 3
x = 2.39
