Answer:
$49,000
Step-by-step explanation:
Donna's net worth is the total value of her assets minus the total value of her liabilities.
Donna's total assets = $142,000 + $1,000 = $143,000
Donna's total liabilities = $63,000 + $18,000 + $13,000 = $94,000
Donna's net worth = $143,000 - $94,000 = $49,000
