To solve this problem, we need to establish the total number of clementines each person brought in terms of bags.
-
Determine the number of clementines brought by Sal and Joe:
- Sal brought 4 bags of clementines. Since each bag has 12 clementines: \[ \text{Clementines from Sal} = 4 \text{ bags} \times 12 \text{ clementines/bag} = 48 \text{ clementines} \]
- Joe brought 6 bags of clementines. Therefore: \[ \text{Clementines from Joe} = 6 \text{ bags} \times 12 \text{ clementines/bag} = 72 \text{ clementines} \]
-
Set up the equation:
- Let \( t \) be the number of bags Trisha brought. The total number of clementines that Trisha brought then is: \[ \text{Clementines from Trisha} = t \text{ bags} \times 12 \text{ clementines/bag} = 12t \text{ clementines} \]
-
Write the equation for the total number of clementines:
- The total number of clementines they all brought is given as 180: \[ 48 + 72 + 12t = 180 \]
Thus, the equation to determine how many bags Trisha brought is: \[ 48 + 72 + 12t = 180 \]
