Final answer:
The total amount of contributed capital when a company issues 600 shares for $45,000 is $45,000.
Step-by-step explanation:
The total amount of contributed capital is the cash value that the company received from issuing its shares. In the student's question, the company issued 600 shares with a $50 par value for a total of $45,000. Since no additional details are provided, such as preferred stock, common stock, or additional paid-in capital, we assume the total contributed capital is equal to the total cash received from the sale of the stock. Thus, the total contributed capital is $45,000.
