Which brand of water is the better buy for Mr. Parsh’s class? Justify y

To determine which brand of water is the better buy, let's calculate the cost per bottle for each brand:

### 1. **Wet Water:**
- Price per case: $8.74
- Bottles per case: 24

\[
\text{Cost per bottle} = \frac{8.74}{24} \approx 0.3642 \quad (\text{rounded to four decimal places})
\]

### 2. **Aquarius Water:**
- Price per case: $11.00
- Bottles per case: 32

\[
\text{Cost per bottle} = \frac{11.00}{32} \approx 0.34375
\]

### Comparison:
- Wet Water: Approximately $0.3642 per bottle
- Aquarius Water: Approximately $0.3438 per bottle

Since $0.3438 < $0.3642, **Aquarius Water** is the cheaper option per bottle.

### Justification:
The cost per bottle of Aquarius Water is lower than that of Wet Water, so **Aquarius Water is the better buy** for Mr. Parsh's class.
