Sure, let's break down the problem step by step.

### Problem Statement
- **Sundae Cost:** $$ \$r $$
- **Chicken Burger Cost:** *times* as much as the sundae (Assuming it costs **2 times** as much based on typical pricing structures)
- **French Fries Cost:** $$ \$3 $$ per box

### Part (a): Total Cost of a Sundae and a Chicken Burger

1. **Cost of a Sundae:** $$ \$r $$
2. **Cost of a Chicken Burger:** Since it costs 2 times as much as the sundae, it's $$ 2r $$
3. **Total Cost:** 
   $$
   \text{Total} = \text{Sundae} + \text{Chicken Burger} = r + 2r = 3r
   $$

**Answer:** The total cost is $$ 3r $$ dollars.

### Part (b): Cost When $$ r = 2 $$

Given:
- $$ r = 2 $$ dollars

1. **Cost of One Chicken Burger:**
   $$
   2r = 2 \times 2 = 4 \text{ dollars}
   $$
2. **Cost of 3 Chicken Burgers:**
   $$
   3 \times 4 = 12 \text{ dollars}
   $$
3. **Cost of 2 Boxes of French Fries:**
   $$
   2 \times 3 = 6 \text{ dollars}
   $$
4. **Total Cost:**
   $$
   12 + 6 = 18 \text{ dollars}
   $$

**Answer:** 3 chicken burgers and 2 boxes of French fries cost **\$18**.
**Part (a):** The total cost of a sundae and a chicken burger is $$ 3r $$ dollars. **Part (b):** When $$ r = 2 $$, 3 chicken burgers and 2 boxes of French fries cost \$18.
