To determine the cost of each bottle of mineral water, follow these steps:

Step 1: Understand the structure

1. Each case contains 2 boxes.
2. Each box contains 4 bottles.
3. Therefore, each case contains: $2 \times 4 = 8 \text{ bottles}.$

Step 2: Calculate the cost per bottle

The total cost of a case is $6.96. Since there are 8 bottles in a case: $\text{Cost per bottle} = \frac{\text{Total cost of a case}}{\text{Number of bottles in a case}} = \frac{6.96}{8}.$

Perform the division: $\text{Cost per bottle} = 0.87 \, \text{dollars}.$

Final Answer:

Each bottle of mineral water costs $0.87.
