Answer:
Opening balance of retained earnings is $667,730
Step-by-step explanation:
The balance of retained earnings at the the end is the sum of opening balance, profit earned and less dividend payment for the period
Retained earnings at the end = Opening balance + profit - dividend
let y represent the opening balance
841, 936 = y + 400,000 - 225,794
y= 841, 936-400,000 + 225,794
y= $667,730
Opening balance of retained earnings = balance sheet on July 1, 2016 is $667, 730
