Let's break down the problem step by step to determine how many pins Brooke has now.

1. **Initial Collection**: Brooke starts with 20 pins.
2. **Pins from Cousins**: Each cousin bought her 4 pins. If we assume she has 3 cousins (as implied by the expression $$3 \cdot 4$$), then the total number of pins she received from her cousins is:
   $$
   3 \cdot 4 = 12
   $$
3. **Total Pins After Receiving**: Now, we add the pins she received from her cousins to her initial collection:
   $$
   20 + 12 = 32
   $$
4. **Pins Given Away**: Brooke then gives away 2 pins to her best friend. So, we subtract these from her total:
   $$
   32 - 2 = 30
   $$

Thus, the expression $$20 + (3 \cdot 4) - 2$$ correctly represents the total number of pins Brooke has now.

Therefore, the final answer is that Brooke has **30 pins** now.
Brooke has 30 pins now.
