Answer:
$800
Step-by-step explanation:
The first task here is to determine the amount of net income recognized in the year which is the earned revenue minus incurred expenses as shown thus:
net income=earned revenue-incurred expenses
earned revenue= $1,100
incurred expenses=$400
net income=$1,100-$400=$700
retained earnings for the period=net income-dividends paid
dividends paid=$200
retained earnings for the period=$700-$200=$500
ending balance of retained earnings=beginning retained earnings+retained earnings for the period
beginning retained earnings=$300
ending balance of retained earnings=$300+$500=$800
