Final answer:
The given transactions of borrowing money and purchasing plant equipment do not affect the company's retained earnings. Retained earnings are influenced by net income and shareholder distributions, not by financing and investing activities. There the correct options is c). No impact.
Step-by-step explanation:
The impact of the transactions on a company's retained earnings can be analyzed as follows:
(a) Borrowing $18,289 from banks to be due in two years is a financing activity and does not affect retained earnings. It increases both the liabilities (loans payable) and the assets (cash) on the balance sheet.
(b) Purchasing additional plant and equipment for $25,000 is an investing activity. This use of cash will decrease the company's assets (cash) and will not affect the retained earnings directly unless it's fully paid from them, which is not indicated.
Neither borrowing money nor purchasing assets directly impacts retained earnings, as these accounts reflect operational performance (net income or loss) rather than financing and investing activities. Therefore, the correct impact of both transactions on the company's retained earnings is:
C) No impact
Retained earnings are primarily changed by net income derived from the company's earnings and by distributions to shareholders in the form of dividends.
