Let space the space number space of space students space be space straight x
hence space cost space per space student space equals space 480 over straight x
now space 8 space of space them space left
hence space cost space per space student space equals space fraction numerator 480 over denominator straight x minus 8 end fraction
by space given space condition
fraction numerator 480 over denominator straight x minus 8 end fraction minus 480 over straight x equals 10
480 straight x minus 480 straight x plus 3840 equals 10 straight x squared minus 80 straight x
straight x squared minus 8 straight x minus 384 equals 0
straight x equals negative 16
straight x equals 24
As space number space of space students space can apostrophe straight t space be space negative space straight x equals 24
so space 16 space students space went.
