Net worth is calculated using the formula:
\[ \text{Net Worth} = \text{Total Assets} - \text{Total Liabilities} \]
Given the data:
- Total Assets = $100,000
- Total Liabilities = $125,000
Now substituting these values into the formula:
\[ \text{Net Worth} = 100,000 - 125,000 \]
Calculating that gives:
\[ \text{Net Worth} = -25,000 \]
Thus, the net worth is
\[ \boxed{-25,000} \]
