y children
50-y adults, 50 combined adults and children
{{{c=15250}}}


{{{350(50-y)+200y=c}}}


Do the algebra steps,...


{{{cross(y=-c/150+116&2/3)}}}
-
recheck:{{{350*50-350y+200y=c}}}
{{{350*50-150y=c}}}
{{{-150y=c-350*50}}}
{{{y=(-c+350*50)/150}}}
-
{{{y=(-15250+350*50)/150=15}}}, {{{fifteen}}}{{{children}}}
