Lia, phil, and cam collect a total of 200.30 dollars for a holiday fundraiser. phil collects 12.80 dollars more than lia. cam collects 3 times as much as lia. how much does each person collect?

 Lia collects $ 37.5 ,  Phil collects  $50.3  and Cam collects dollars $ 112.5 .

Step-by-step explanation:

Let us assume that the dollar collect by the Lia be x .

As given

Lia, Phil, and Cam collect a total of 200.30 dollars for a holiday fundraiser.

Phil collects 12.80 dollars more than Lia.

Phil collects dollars = 12.80 + x

As given

Cam collects 3 times as much as Lia.

Cam collects dollars = 3x

Than the equation becomes

x + 12.80 + x + 3x  = 200.30

12.80 +  5x  = 200.30

5x =  200.30 - 12.80

5x = 187.5

x = $ 37.5

Thus

Lia collects dollars =  $ 37.5

Phil collects dollars = 12.80 + 37.5

                                = $50.3  

Cam collects dollars = 3 × 37.5

                                  = $ 112.5

Therefore the  Lia collects $ 37.5 ,  Phil collects  $50.3  and Cam collects dollars $ 112.5 .

i believe the answer is the polygon, heptagon.
