### **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?**  
💡 **Solve using a Bar Model, Double Number Line, or Equations.**  

✅ **Remember:**  
- "Explain your thought process after solving each part."  
- "Try your best before I give hints!"

Does this setup make sense to you?"
