Bags of clementines have 12 each. For a party, Sal, Trisha, and Joe each brought bags of clementines. Altogether, there were 180 clementines. Sal brou
ght twice as many bags as Trisha, and Joe brought 3 bags. How many bags of clementines did each person bring?
Let's assume Trisha brought x bags of clementines.
So Sal brought 2x bags of clementines.
Joe brought 3 bags of clementines.
The total number of clementines is 12(x) + 12(2x) + 12(3) = 180.
So, 12x + 24x + 36 = 180.
36x + 36 = 180
36x = 180 - 36
36x = 144
x = 144/36
x = 4
So Trisha brought 4 bags of clementines, Sal brought 2*4 = <<2*4=8>>8 bags of clementines, and Joe brought 3 bags of clementines. Answer: \boxed{4,8,3}.
