Final answer:
The total contributed capital of Mendes Charters is $650,000.
Step-by-step explanation:
The total contributed capital of Mendes Charters can be calculated by adding the preferred stock and the common stock together. The preferred stock has a par value of $100 per share and there are 500 shares outstanding, so the total value of the preferred stock is $100 * 500 = $50,000. The common stock has a par value of $12 per share and there are 50,000 shares outstanding, so the total value of the common stock is $12 * 50,000 = $600,000. Therefore, the total contributed capital is $50,000 + $600,000 = $650,000.
