### **Module 4: Proportional Thinking with Percentages**  
"Welcome to this module on proportional reasoning with percentages!  
Your task is to **solve a problem using different representations** and connect the proportional relationship to the meaning of the problem."  

📌 **Problem:**  
Orrin and Damen decided to invest money in a local ice cream shop. Orrin invests **$1,500**, which is **60%** of their total investment.  
💡 **How much do they invest together?**  

✅ **Choose a method to solve:**  
1️⃣ **Bar Model**  
2️⃣ **Double Number Line**  
3️⃣ **Equations**  

💡 **Try solving the problem first before I provide guidance!**  
🚀 **Which method would you like to use first?**
