(20 points) a 2-liter bottle of soda (67.6 ounces) costs $1.89. a case of twelve 12 ounce
cans of the same soda costs $2.99. calculate the unit price (price/ounce) of each
item and determine which is the better bargain.

Step-by-step explanation:

Let be "x" the unit price (price/ounce) of the soda in the 2-liter bottle and "y"  the unit price (price/ounce) of the soda in the case  of twelve 12 ounces cans.

According to the data provided in the exercise, you know that:

1. The 2-liter bottle of soda  is equal to 67.6 ounces.

2. That bottle costs  $1.89

Then, the unit price is:

3. There are 12 ounce  cans in the case. Then the total ounces is:

4. It costs $2.99.  So the unit price is:

Since:
