**Problem (a): Jerry’s Pizza Coupons**

1. Jerry starts with $$12$$ coupons.
2. He uses $$8$$ coupons.
3. The remaining coupons are found by subtracting:  
   $$
   12 - 8
   $$
4. This situation directly involves taking away a number from another.

Thus, the subtraction model that best corresponds to this problem is **Take-away**.

**Problem (b): Maggie’s Hike**

1. The total distance of the hike is $$14$$ miles.
2. A sign indicates that there are $$6$$ miles remaining.
3. The distance Maggie has already walked is the missing part in the equation:  
   $$
   \text{Walked distance} + 6 = 14
   $$
4. To find the walked distance, we subtract:  
   $$
   \text{Walked distance} = 14 - 6
   $$
5. This problem is solved by finding the missing addend.

Thus, the subtraction model that best corresponds to this problem is **Missing addend**.
**Problem (a): Take-away** **Problem (b): Missing addend**
