    220=A+S (adult plus student)

    s=220-a

    2.50a+1.50s=465

    1.50s=-2.50a+465

    s=-1.67a+310

    then set those equal to each other

    220-a=-1.67a+310

    220=-.67a+310

    -90=-.67a

    .67a=90

    a=60

    then put a back into the first equation

    220=S+A

    220=s+60

    s=160

    a=60, s=160
