### Applying the Sorted Edges Algorithm

#### Graph Explanation

The image shows a weighted graph with four vertices labeled \(A\), \(B\), \(C\), and \(D\). The edges connecting these vertices have the following weights:

- Edge \(A - C\): 1
- Edge \(A - D\): 5
- Edge \(A - B\): 10
- Edge \(C - D\): 14
- Edge \(C - B\): 6
- Edge \(D - B\): 15

#### Problem Statement
**Task**: Apply the sorted edges algorithm to the graph above. Find the total cost of the resulting circuit.

### Steps Using the Sorted Edges Algorithm

1. **List the Edges in Order of Increasing Weight**:
   - \(A - C\): 1
   - \(A - D\): 5
   - \(C - B\): 6
   - \(A - B\): 10
   - \(C - D\): 14
   - \(D - B\): 15

2. **Select Edges to Form a Circuit**:
   The sorted edges algorithm involves selecting edges in order of increasing weight, ensuring that no cycles are formed until all vertices are connected.

   - Select edge \(A - C\) (Weight 1)
   - Select edge \(A - D\) (Weight 5)
   - Select edge \(C - B\) (Weight 6)

   At this point, we have connected all vertices: \(A\), \(B\), \(C\), \(D\). Note that selecting the edge \(A - B\) would form a cycle.


#### Total Cost Calculation

The selected edges are:

- \(A - C\) (Weight 1)
- \(A - D\) (Weight 5)
- \(C - B\) (Weight 6)

**Total Cost** = 1 + 5 + 6 = 12

Therefore, the total cost of the resulting circuit is **12**.
