### **Module 4: Proportional Thinking with Percentages**  
"Welcome to this module on **proportional reasoning with percentages**!  
Your goal is to solve a real-world problem using **different representations** and connect proportional relationships 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**  

💡 **First, try solving the problem on your own before I provide guidance!**

"Let’s confirm the answer together!"  

📌 **Bar Model Representation**  
Understanding the Problem:  
- Orrin invests **$1,500**, which is **60%** of the total investment.  
- We need to find **100% of the total investment**.  

📌 **Creating the Bar Model**  
- Draw a **horizontal bar** and divide it into **10 equal parts**.  
- Label **6 parts** as Orrin’s 60% ($1,500).  
- The remaining **4 parts** represent Damen’s investment (40%).  

📌 **Calculating the Total Investment**  
Since Orrin’s $1,500 represents **60%**, we set up the proportion:  
\\[
\\text{Total Investment} = \\frac{1500}{0.6}
\\]  
Solving for total investment:  
\\[
\\text{Total Investment} = 2500
\\]  

📌 **Conclusion:**  
The total investment made by Orrin and Damen together is **$2,500**.  

💡 **Reflection:**  
- "How did the bar model help your understanding?"  
🚀 **Would you like to try another method, such as a Double Number Line?**

- **Step 2:** The other represents **dollars** ($0, $1,500, total investment).  
- **Step 3:** Find the value of **10%** by dividing **$1,500 by 6**.  

💡 **What do you think the total investment is?**  
"""

    elif step == 7:
        return """✅ **Solution Using Double Number Line**  
📌 **Double Number Line Representation**  
- Mark key points on two parallel lines:  
  - **0%, 60%, 100%** on one line.  
  - **$0, $1,500, and Total Investment** on the other.  
- Since **$1,500 represents 60%**, divide by **6** to get **10% = $250**.  
- Multiply by **10** to get **100% = $2,500**.  

📌 **Conclusion:**  
The total investment is **$2,500**.

💡 **What do you get?**

📌 **Equation Representation**  
Using a proportion:  
\\[

Cross-multiply:  
\\[
60x = 1500 \\times 100

Divide both sides by **60**:

The total investment is **$2,500**.
