To determine how many bags of clementines Trisha brought, we can first define some variables:
- Let \( T \) be the number of bags Trisha brought.
- Let \( J \) be the number of bags Joe brought.
We know that each bag contains 12 clementines. Therefore, the total number of clementines brought by Trisha and Joe can be expressed as:
\[ 12T + 12J = 180 \]
Since Sal brought 4 bags and each bag contains 12 clementines, the total number of clementines Sal brought can be calculated as follows:
\[ 12 \times 4 = 48 \]
Now, we can subtract the clementines brought by Sal from the total clementines to find the clementines brought by Trisha and Joe:
\[ 180 - 48 = 132 \]
Thus, the equation for the clementines brought by Trisha and Joe becomes:
\[ 12T + 12J = 132 \]
To simplify the equation, we can divide everything by 12:
\[ T + J = 11 \]
Now that we have the equation \( T + J = 11 \), we can express the number of bags Trisha brought in terms of the number of bags Joe brought:
\[ T = 11 - J \]
We need more information about how many bags Joe (or Trisha) brought to find the exact number of bags Trisha brought. If you have that information, please provide it!
