Answer:
$423,360
Step-by-step explanation:
Equity which represents the amount owed to the owners of the business includes retained earnings (which is the accumulation of the net income/loss over the years less dividends paid) and common shares.
Ending retained earnings = Beginning retained earnings + additional stock issued + net income - dividend paid
net income is the difference between sales and expenses
= $406080 + $57600 - $34560 - $5760
= $423,360
