A merchant borrowed $12,000$ dinars at a simple interest rate of $8\%$ and invested it in a project that yielded $14\%$ annually. What was the net profit after one year?
7. Find the Function Domain:
A person invested money in a project that yielded a fixed annual return of $12\%$. At the same time, he borrowed another sum from a bank at a simple annual interest rate of $8\%$. If the invested amount was $15,000$ dinars and the borrowed amount was $10,000$ dinars, what was the net profit after one year?
استثمر شخص مبلغاً من المال في مشروع يحقق عائداً سنوياً ثابتاً قدره $\%12$. وفي نفس الوقت اقترض من بنك مبلغاً آخر بفائدة بسيطة سنوية $\%8$. إذا كان المبلغ المستثمر يساوي $15,000$ دينار والمبلغ المقترض $10,000$ دينار، فما الربح الصافي بعد سنة واحدة؟
Find the Function Domain:
$f(x) = \frac{2x - 1}{1 - \sqrt{x - 5}}$
Find the Function Domain: $g(x) = \sqrt{2 - \sqrt{x + 3}}$
