**Problem 1: Shortest Path in a Network**

The diagram presented is a network graph consisting of seven nodes interconnected by directed edges, each labeled with a numerical value representing the "cost" or "weight" of traversing that edge. Your objective is to find the shortest (minimum cost) path from Node 1 to Node 7.

### Node Connections and Costs:

- **Node 1**: 
  - Connects to Node 2 with a cost of 5.
  - Connects to Node 3 with a cost of 6.
  - Connects to Node 4 with a cost of 6.

- **Node 2**:
  - Connects to Node 3 with a cost of 2.5.
  - Connects to Node 5 with a cost of 4.

- **Node 3**:
  - Connects to Node 4 with a cost of 3.
  - Connects to Node 6 with a cost of 2.

- **Node 4**:
  - Connects to Node 6 with a cost of 3.

- **Node 5**:
  - Connects to Node 6 with a cost of 2.
  - Connects to Node 7 with a cost of 8.

- **Node 6**:
  - Connects to Node 7 with a cost of 7.

### Task:
Your task is to calculate the shortest path from Node 1 to Node 7. The previously suggested possible answer is a total minimum cost of 16. Use a problem-solving approach similar to the one applied in earlier problems.

**Hint**: You may find graph algorithms like Dijkstra’s algorithm useful for solving this problem efficiently. Analyze the given paths and compute the total costs to determine the optimal one.
