I need help with this question

The Basu Group reacquired 3 million of its shares at $62 per share as treasury stock Last year, for the first time, Elasu sold 1 million treasury shares at $63 per share. If Basu now sells the remaining 2 million treasury shares at $59 per share, by what amount will retained earnings decline? Note: Enter your answer in millions (1.e., 10,000,000 should be entered os 10)
