Answer:
$15,000
Explanation:
A person's net worth is the difference between their total assets and total liabilities.
In this case,
Assets are
House $100,000
Savings $5,000
Car $10,000
Total assets= $115,000
Liabilities
mortgage of $90,000,
car loan $7,000
credit card debt $3,000
Total liabilities= $100,000
Net worth = Total assets - Total liabilities
=$115,000 - $100,000
=$15,000
