Answer:
a. The value of shareholder's equity account for this firm is $16,600.
b. The net working capital for Wims Inc. is $1,500.
a. We start off by looking at the Accounting Identity:
![Total Assets = Total Liabilities + Shareholders' Equity](https://img.qammunity.org/2019/formulas/business/college/6fr27dm8habstnrl2m967fyp8ltph81yat.png)
Since
![Total Assets = Current Assets + Net Fixed Assets](https://img.qammunity.org/2019/formulas/business/college/n4ubhhjhp7zigt5xyl0z3kkre627v7kjdc.png)
and
![Total Liabilities = Current Liabilities + Long-term debt](https://img.qammunity.org/2019/formulas/business/college/8vymzzuzf3yhayquyatp2qmdnlhp7zogow.png)
We can rewrite this accounting identity as follows:
----- (1)
Plugging in the values from the question in (1) above we get,
![5000 +23000 = 3500 + 7900 + Share holders' equity](https://img.qammunity.org/2019/formulas/business/college/pznsrpsmnmhfnmfqseg7xr9owwn57lgzxx.png)
![28000 = 11400 + Share holders' equity](https://img.qammunity.org/2019/formulas/business/college/3md7yy35hq1dpib73lec7s4d359vk3dzxg.png)
![28000 - 11400 = Share holders' equity](https://img.qammunity.org/2019/formulas/business/college/r8lk13lntchdgtcfkyfjpkkwav43k8dhp8.png)
![Share holders' equity = $16,600](https://img.qammunity.org/2019/formulas/business/college/qzfgvqfudnz9jcspjxm3381dwgxu9emix6.png)
b. The formula for Net Working Capital is:
![Net Working Capital = Current Assets - Current Liabilities](https://img.qammunity.org/2019/formulas/business/college/jyihcnyhdfml2mf7z7ms6jril74fgb36yw.png)
![Net Working Capital = 5000 - 3500](https://img.qammunity.org/2019/formulas/business/college/ye4vpszj0vrmltcqjhjyf9mp0arrlfl9v4.png)
![Net Working Capital = $1500](https://img.qammunity.org/2019/formulas/business/college/az381xte4ivoh0a46kjhu2n9otdopj24oy.png)
