<u>Answer: </u>
The amount collected by lia, phil and cam are $37.5, $50.3 and $112.5 respectively.
<u>Explanation:</u>
Amount collected by Lia, Phil, and Cam for a holiday fundraiser= $200.30
Let the amount collected by lia be $n.
Phil collects $12.80 more than Lia.
Then, amount collected by phil will be $(n + 12.8)
Cam collects 3 times as much as Lia.
Then, amount collected by cam will be $3n
Now, we know that, total amount = $200.3
Lia amount + phil amount + cam amount = 200.3
n + n + 12.8 + 3n = 200.3
5n = 200.3 – 12.8
5n = 187.5
n = 37.5
Then , amount collected by phil will be
$(n + 12.8) = $(37.5 + 12.8) = $50.3 and
The amount collected by cam will be
$3n = $(37.5 x 3) = $112.5
