Let's break this down step by step:

1. Start with the given expression:  
   \[ 30 + (0.0825 \times 30) + (0.15 \times 30) \]

2. Calculate each part:
   - \( 0.0825 \times 30 = 2.475 \)
   - \( 0.15 \times 30 = 4.5 \)

3. Now, add everything together:
   \[ 30 + 2.475 + 4.5 = 36.975 \]

The result is **36.975**.
