📌 **Problem 1: Missing Value Problem**
**Problem:**
*"The scale on a map is 2 cm represents 25 miles. If a given measurement on the map is 24 cm, how many miles are represented?"*
### **Solution Strategy:**
1️⃣ **Understand the Scale:**
- You know that **2 cm** on the map corresponds to **25 miles** in reality.
2️⃣ **Set Up a Proportion:**
$$
\frac{2 \,\text{cm}}{25 \,\text{miles}} = \frac{24 \,\text{cm}}{x \,\text{miles}}
$$
3️⃣ **Cross-Multiply and Solve:**
$$
2x = 24 \times 25
$$
4️⃣ **Calculate:**
$$
x = \frac{24 \times 25}{2} = 300 \text{ miles}
$$
**Conclusion:** *24 cm on the map represents **300 miles**.*

📌 **Problem 2: Numerical Comparison Problem**
**Problem:**
*"Ali and Ahmet purchased pencils. Ali bought **10 pencils for $3.50**, and Ahmet purchased **5 pencils for $1.80**. Who got the better deal?"*
### **Solution Strategy:**
1️⃣ **Calculate the Unit Price for Each:**
$$
\text{Cost per pencil for Ali} = \frac{\$3.50}{10} = \$0.35
$$
$$
\text{Cost per pencil for Ahmet} = \frac{\$1.80}{5} = \$0.36
$$
2️⃣ **Compare the Unit Prices:**
- **Ali pays \$0.35 per pencil**
- **Ahmet pays \$0.36 per pencil**
3️⃣ **Conclusion:** *Ali got the better deal because he paid **less per pencil**.*

📌 **Problem 3: Qualitative Reasoning Problem**
**Problem:**
*"Kim is mixing paint. Yesterday, she combined **red and white paint** in a certain ratio. Today, she used **more red paint** but kept the **same amount of white paint**. How will today’s mixture compare to yesterday’s in color?"*
### **Solution Strategy:**
1️⃣ **Understand the Change in Ratios:**
- Today, the **amount of red paint has increased**, while **white paint remains constant**.
2️⃣ **Qualitative Analysis:**
- Since **the proportion of red paint has increased**, today's mixture will be **more red (darker)** compared to yesterday.
