### Part 1:
To model the total cost $$ C $$ based on the number of miles driven $$ m $$, you start with a fixed cost of \$30 and add 45 cents (or \$0.45) for each mile driven. The correct equation representing this relationship is:

$$
C = 0.45m + 30
$$

**Correct Model:**  
$$ C = 0.45m + 30 $$

### Part 2:
To find the total cost for driving 350 miles, substitute $$ m = 350 $$ into the equation:

$$
C = 0.45 \times 350 + 30
$$

Calculate the mileage cost:
$$
0.45 \times 350 = 157.50
$$

Add the fixed cost:
$$
157.50 + 30 = 187.50
$$

**Total Cost for 350 Miles:**  
$$\$187.50$$
**Part 1:** The correct equation is $$ C = 0.45m + 30 $$. **Part 2:** The total cost for driving 350 miles is \$187.50.
