Answer:
retained earning balance = $12,200
correct option is b. $12,200
Explanation:
given data
retained earnings balance = $10,000
common stock = $5,000
Provided services on account = $3,000
Provided services in exchange for cash = $900
Purchased equipment and paid cash= $4,300
Paid rent = $800
Paid workers salaries = $900
solution
we know sale is here
Sales = 3000 + 900 = 3900
Expenses = 800 + 900 = 1700
So that sales less expenses is profit of 3900 - 1700 = $2200
so retained earning balance = $10,000 + $2200
retained earning balance = $12,200
correct option is b. $12,200
