To determine which is the better buy, we need to calculate the price per kilogram for each bag of red onions.

1. **For the 2-kilogram bag**:
   \[
   \text{Price per kilogram} = \frac{4.76}{2} = 2.38 \, \text{dollars per kilogram}
   \]

2. **For the 5-kilogram bag**:
   \[
   \text{Price per kilogram} = \frac{11.60}{5} = 2.32 \, \text{dollars per kilogram}
   \]

### Conclusion:
The **5-kilogram bag** is the better buy because it costs **$2.32 per kilogram**, which is slightly cheaper than the **2-kilogram bag** at **$2.38 per kilogram**.
