Answer:
It is obvious that the requirement is the retained earnings at end of the year since the opening retained earnings and year's transactions were provided.
Closing retained earnings is $11,400
Step-by-step explanation:
The net income for the year is calculated thus:
Sales($2000+$900) $2,900
less expenses:
rent paid ($800)
salaries ($700)
Net income $1400
Hence closing retained earnings is opening retained earnings of $10,000 plus the net income realized in the year,which $11,400($10,000+$1,400).
The retained should be added to the share capital to arrive at shareholders' equity.
