To determine how many bags Trisha brought, we can start by calculating the total number of clementines brought by Sal and Joe.
Each bag contains 12 clementines, so:
-
Sal brought 4 bags:
\( 4 \text{ bags} \times 12 \text{ clementines/bag} = 48 \text{ clementines} \) -
Joe brought 6 bags:
\( 6 \text{ bags} \times 12 \text{ clementines/bag} = 72 \text{ clementines} \)
Now, we can calculate the total number of clementines brought by Sal and Joe combined: \[ 48 + 72 = 120 \text{ clementines} \]
We know that the total number of clementines is 180. Let \( t \) be the number of bags Trisha brought. The total number of clementines Trisha brought is \( 12t \).
Now we can set up the equation: \[ 48 + 72 + 12t = 180 \]
Simplifying that, we have: \[ 120 + 12t = 180 \]
To find \( t \), subtract 120 from both sides: \[ 12t = 60 \]
Now, divide by 12: \[ t = 5 \]
So, Trisha brought 5 bags of clementines.
