First, we need to find out how many clementines Sal and Joe brought and then determine how many bags Trisha brought.
-
Calculate the number of clementines brought by Sal and Joe:
- Each bag contains 12 clementines.
- Sal brought 4 bags, so he delivered:
\( 4 \text{ bags} \times 12 \text{ clementines/bag} = 48 \text{ clementines} \). - Joe brought 6 bags, therefore he provided:
\( 6 \text{ bags} \times 12 \text{ clementines/bag} = 72 \text{ clementines} \).
-
Calculate the total number of clementines brought by Sal and Joe:
- Total from Sal and Joe:
\( 48 + 72 = 120 \text{ clementines} \).
- Total from Sal and Joe:
-
Determine how many clementines Trisha brought:
- The total number of clementines is 180, so the number of clementines that Trisha brought is:
\( 180 - 120 = 60 \text{ clementines} \).
- The total number of clementines is 180, so the number of clementines that Trisha brought is:
-
Set up the equation for the number of bags Trisha brought:
- Let \( t \) be the number of bags Trisha brought. Then: \( 12t = 60 \).
Finally, putting it all together, we write the equation as:
\( t + 10 = 15 \) or equivalently \( 12t = 60 \).
Thus, the equation is:
\( t = 5 \), which means Trisha brought 5 bags of clementines.
