Explanation:
To get 4 bottles of juice and 7 bottles of soda, it would cost:
4 bottles of juice * $1.40/bottle = $5.60
7 bottles of soda * $1.20/bottle = $8.40
The total cost would be $5.60 + $8.40 = $14.00
For xx bottles of juice and y bottles of soda, it would cost:
xx bottles of juice * $1.40/bottle = $1.40 * xx
y bottles of soda * $1.20/bottle = $1.20 * y
The total cost would be $1.40 * xx + $1.20 * y.
