To determine how many bags Trisha brought, we can start by setting up an equation based on the information given.
- Let \( x \) represent the number of bags Trisha brought.
- Each bag contains 12 clementines. Therefore:
- Sal brought 4 bags, contributing \( 4 \times 12 = 48 \) clementines.
- Joe brought 6 bags, contributing \( 6 \times 12 = 72 \) clementines.
- Trisha brought \( x \) bags, contributing \( x \times 12 \) clementines.
Now we can write the equation for the total number of clementines:
\[ 48 + 72 + 12x = 180 \]
Now, combine the constants:
\[ 120 + 12x = 180 \]
This is the equation you can use to determine how many bags Trisha brought. From here, you can solve for \( x \).
