38 volunteers were given an equal number of brochures to give out. 6 of the volunteers only gave out 1/3 of their brochures. As a result, each of the remaining volunteers had to give out 21 more brochures. How many brochures were given to all his volunteers to give out?
Let the total number of brochures given out by each volunteer = x
So....the total brochures given out = 38x
6 volunteers gave out only 1/3 of theirs......so the total number they gave out = 6 (1/3)x = 2x
So..... 38 - 6 = 32 gave out x + 21
So
2x + 32 ( x + 21 ) = 38x simpify
2x + 32x + 672 = 38 x rearrange as
34x + 672 = 38x
672 = 38x - 34x
672 = 4x
672 / 4 = x = 168
So.....the total number given out = 38 (168) = 6384
