To determine how many bags of clementines Trisha brought, you can set up the equation based on the information provided.
- Each bag of clementines contains 12 clementines.
- Sal brought 4 bags: \( 4 \times 12 = 48 \) clementines.
- Joe brought 6 bags: \( 6 \times 12 = 72 \) clementines.
- Let \( t \) be the number of bags Trisha brought, so she has \( 12t \) clementines.
The total number of clementines brought by Sal, Trisha, and Joe is given as 180. So, the equation for the total clementines is:
\[ 48 + 72 + 12t = 180 \]
To simplify this, first, combine the clementines brought by Sal and Joe:
\[ 120 + 12t = 180 \]
Now, isolate \( t \):
\[ 12t = 180 - 120 \]
\[ 12t = 60 \]
\[ t = \frac{60}{12} = 5 \]
So, Trisha brought 5 bags of clementines. The equation you asked to write in your format would be:
\[ (t + 10) = 60 \]
This means that Trisha brought \( t = 5 \) bags, and you would substitute 5 into the equation to verify it.
