Certainly! Let's break down the problem step by step.

### **Given:**
- **Total Cost Function:** $$ y = 21x + 13 $$
- **Variables:**
  - $$ y $$: Total cost in dollars
  - $$ x $$: Number of tickets purchased

### **Understanding the Equation:**
- **$$ 21x $$:** This represents the cost of the tickets themselves. Each ticket costs \$21, so if Joe buys $$ x $$ tickets, the total cost for the tickets is $$ 21x $$.
- **$$ +13 $$:** This is a fixed additional cost, perhaps for service fees or taxes, totaling \$13 regardless of the number of tickets bought.

### **Setting Up the Problem:**

Suppose we want to **find the total cost** for a specific number of tickets. Let's choose an example where Joe buys **5 tickets**.

### **Step-by-Step Solution:**

1. **Identify the number of tickets ($$ x $$):**
   $$
   x = 5 \text{ tickets}
   $$

2. **Plug $$ x $$ into the total cost function:**
   $$
   y = 21x + 13
   $$
   $$
   y = 21(5) + 13
   $$

3. **Calculate the total cost:**
   $$
   y = 105 + 13
   $$
   $$
   y = 118
   $$

### **Conclusion:**
- **Total Cost ($$ y $$)** for **5 tickets** is **\$118**.

### **General Formula:**
If you want to find the total cost for any number of tickets, simply replace $$ x $$ with the desired number of tickets in the equation $$ y = 21x + 13 $$.

**Example:**  
If Joe buys **10 tickets**:
$$
y = 21(10) + 13 = 210 + 13 = 223
$$
So, the total cost would be **\$223**.

### **Summary:**
The equation $$ y = 21x + 13 $$ effectively calculates the total cost based on the number of tickets purchased, accounting for both the variable cost per ticket and the fixed additional fee.
To find the total cost $$ y $$ for $$ x $$ tickets, use the equation $$ y = 21x + 13 $$. For example, buying 5 tickets costs \$118.

Joe bought Timberwolves tickets. The total cost, \( y \), in dollars, \( x \) tickets can be found using the function \( y=21 x+13 \). Choose the correct setup and solve.
