Diana and russ ate a meal costing 31.20 when they went out to dinner. If they want to leave a 20% tip for their server, how much will they tip and what will their total be?

To find the tip and the total amount Diana and Russ will pay, we can follow these steps:

1. **Calculate the tip:**
   The tip is 20% of the cost of the meal.  
   Tip = 20% of $31.20 = $ \frac{20}{100} \times 31.20 = 0.20 \times 31.20 = 6.24 $

2. **Calculate the total amount:**
   Total amount = Cost of the meal + Tip  
   Total = $31.20 + $6.24 = $37.44

### Answer:
- **Tip amount:** $6.24
- **Total amount:** $37.44
