Answer: $3.4 million
Step-by-step explanation:
The increase in Retained earnings is the net earnings for the year.
Net earnings are calculated by deducting dividends from the Net income.
Net earnings = Net income - Dividends
1,700,000 = 5,100,000 - Dividends
Dividends = 5,100,000 - 1,700,000
= $3,400,000
= $3.4 million
