Bags of clementine have 12 each. For a party sal Trish and Joe each bought bags of clementines although there were 180 clementines, so bought four bags and Joe bought six write an equation to determine how many bags Trish brought t.
Let t be the number of bags that Trish brought. Since each bag of clementines has 12 clementines, Trish brought 12t clemetines.
Joe brought 6 bags, so he brought 12*6 = <<6*12=72>>72 clementines.
Sal and Trish brought a total of 180-72 = <<180-72=108>>108 clementines.
Since Sal and Trish bought a total of 4 bags, and Trish brought t bags, Sal brought 4-t bags.
Sal brought 12*(4-t) = 48-12t clementines.
The total number of clementines is the sum of what Sal and Trish brought: 12t + 48-12t = 108.
This simplifies to 48 = 108, so the answer is t = <<60=60>>60. Answer: \boxed{60}.
