    Lia=L

    Phil=12.80+L

    Cam=3L

    L+12.80+L+3L=200.30

    5L+12.80=200.30

    5L=200.30-12.80

    5L=187.5

    L=187.5/5

    Plug into the equations at the top

    L=Lia=$37.5

    Phil=12.80+37.5=$50.30

    Cam=3 (37.5) = $112.50

    Lia:$37.50

    Phil:$50.30

    Cam:$112.50

    First you make a chart with all the people and total. Lia is x, Cam is 3x, and Phil is x+12.80. Then you make an equation: x+x+12.80+3x=200.30. Then you solve for x.
