To find out how many bags of clementines Trisha brought, we can first establish the total number of clementines brought by Sal and Joe and then set up an equation with the number of bags Trisha brought.
Each bag contains 12 clementines.
-
Calculate the number of clementines brought by Sal:
- Sal brought 4 bags, so the number of clementines he brought is: \( 4 \text{ bags} \times 12 \text{ clementines/bag} = 48 \text{ clementines} \)
-
Calculate the number of clementines brought by Joe:
- Joe brought 6 bags, so the number of clementines he brought is: \( 6 \text{ bags} \times 12 \text{ clementines/bag} = 72 \text{ clementines} \)
-
Calculate the total number of clementines brought by Sal and Joe: \( 48 \text{ (Sal)} + 72 \text{ (Joe)} = 120 \text{ clementines} \)
-
Determine the total number of clementines brought to the party:
- The total number of clementines is 180.
-
Determine the number of clementines brought by Trisha:
- The number of clementines Trisha brought is: \( 180 - 120 = 60 \text{ clementines} \)
-
Convert that back into bags for Trisha: To find the number of bags (t) that Trisha brought: \[ t \text{ bags} \times 12 \text{ clementines/bag} = 60 \text{ clementines} \] This simplifies to: \[ t = \frac{60}{12} = 5 \text{ bags} \]
Now we can write the equation to determine how many bags Trisha brought, \( t \):
\[ (t + 10) = 15 \]
Thus, the equation is: \[ (t + 10) = 15 \]
This indicates Trisha brought 5 bags, since \( t = 5 \).
