Given, the amount Megan has in short term savings = $500.
The amount in retirement savings account = $5000.
The amount in credit card debt = $500.
The amount in student loan debt = $6500.
So total assets of Megan = Sum of short term savings and retirement savings.
Total asset = $500 + $5000 = $
= $

Total liabilities of Megan = sum of credit card debt and student loan debt.
Total liability = $ 500 + $6500 = $
= $

Now to find Megan's net worth we have to subtract total liability from total asset.
So Megan's net worth = $5500-$7000 = $
= $

So we have got the required answer.
Net worth of Megan = -$1500.
