To evaluate the expression $$ 12.5b + 6(10 + b) $$ when $$ b = 4 $$:

1. **Substitute $$ b $$ with 4:**
   $$
   12.5(4) + 6(10 + 4)
   $$

2. **Calculate each part:**
   $$
   12.5 \times 4 = 50
   $$
   $$
   6 \times (10 + 4) = 6 \times 14 = 84
   $$

3. **Add the results:**
   $$
   50 + 84 = 134
   $$

So, the value of the expression when $$ b = 4 $$ is **\$134**.

**Answer:** D. $$ \$134 $$
When $$ b = 4 $$, the expression equals \$134.
