To find the unit rate in dollars per pound, we need to divide the total cost by the total weight in pounds.

1. **Known conditions:**
   - Total cost of apples = $$ 9 $$ dollars
   - Total weight of apples = $$ 3 $$ pounds

2. **Calculate the unit rate:**
   $$
   \text{Unit rate} = \frac{\text{Total cost}}{\text{Total weight}} = \frac{9}{3}
   $$

Now, let's perform the calculation:

$$
\text{Unit rate} = 3 \text{ dollars per pound}
$$

Thus, the unit rate is $$ 3 $$ dollars per pound.
The unit rate is \$3 per pound.
