To find $$ a_{30} $$ for the sequence defined by $$ a_{n} = 9.9 - 3.2n $$, follow these steps:

1. **Substitute $$ n = 30 $$ into the formula:**
   $$
   a_{30} = 9.9 - 3.2 \times 30
   $$

2. **Calculate the multiplication:**
   $$
   3.2 \times 30 = 96
   $$

3. **Subtract the result from 9.9:**
   $$
   a_{30} = 9.9 - 96 = -86.1
   $$

**Therefore, $$ a_{30} = -86.1 $$.**

**Correct Answer:** ○ **-86.1**
$$ a_{30} = -86.1 $$
