**Reiny**, Tuesday, December 11, 2012 at 8:52pmnumber of votes --- x

Alyssa gets (2/7)x

leaving 5x/7

Bert gets 65% of that or .65(5x/7)

Cara gets x - 2x/7 - .65(5x/7)

but that is 315

x - 2x/7 - .65(5x/7) = 315

times 7

7x - 2x - .65(5x) = 315

1.75x = 2205

x = 1260 ----> number of votes

check:

Alyssa gets (2/7)1260 = 360

leaving 900 votes

Bert gets 65% of 900 = 585

Carla gets 1260 - 360 - 585 = 315

All is good!
