Travis collected 43. To find what Jessica collected, you do 43 - (43*0.20) = 34.4 or $34.40. To find what Robin collected, you do 43 + (43*0.35) = 58.05 or $58.05.
Add these together: 43.00 + 34.40 + 58.05 = 135.45.
$135.45 were collected in total assuming everyone collected exactly the percentage they 'wanted' to.
