total of  votes: 1600-> this means votes for Martha plus the votes for Hillary

If we divide 1600 by 2 people, this leaves 800 votes for each girl.

800-81=719 for Hillary    
800+81=881 for Martha

We take 81 votes, from those 800,and place them in martha's votes

Just to confirm: 881+719=1600 total votes
