**Damon**, Wednesday, December 26, 2012 at 4:41pmb = g - 165

2 g/7 = 3 b/5

2 g/7 = (3/5)(g-165)

solve for g

then for b

then add b+g

**drwls**, Thursday, December 27, 2012 at 7:43amThere are g girls and b boys.

2 g/7 = (3/5)(g-165)

(See Damon's derivation)

(10/21)g = g - 165

11/21 g = 165

g = 315

b = 315 -165 = 150

Total = b + g = 465
