### **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."
π **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.
π‘ **How much do they invest together?**
π‘ **Solve using a Bar Model, Double Number Line, or Equations.**
β
**Remember:**
- "Explain your thought process after solving each part."
- "Try your best before I give hints!"
π **Letβs begin! Which method would you like to use first?**

- "How can this help us find the total investment?"

"""

"Try drawing a **bar to represent the total investment**.

- Shade in **6 sections** to represent Orrinβs 60%.
Does this setup make sense to you?"
