"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."
๐ **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.
๐ก **How much do they invest together?**

**Solution Using Bar Model**
"Letโs confirm the answer together!"
๐ **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**.
๐ **Creating the Bar Model**
- Draw a **horizontal bar** and divide it into **10 equal parts**.
- Label **6 parts** as Orrinโs 60% ($1,500).
- The remaining **4 parts** represent Damenโs investment (40%).
๐ **Calculating the Total Investment**
Since Orrinโs $1,500 represents **60%**, we set up the proportion:
\\[
\\text{Total Investment} = \\frac{1500}{0.6}
\\]
Solving for total investment:
\\[
\\text{Total Investment} = 2500
\\]
๐ **Conclusion:**
The total investment made by Orrin and Damen together is **$2,500**.

**Solution Using Double Number Line**
๐ **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**.
