To find out how many bags of clementines Trisha brought, we can start by determining how many clementines Sal and Joe brought.
-
Calculate the number of clementines Sal brought: \[ \text{Clementines from Sal} = \text{bags brought by Sal} \times \text{clementines per bag} = 4 \times 12 = 48 \]
-
Calculate the number of clementines Joe brought: \[ \text{Clementines from Joe} = \text{bags brought by Joe} \times \text{clementines per bag} = 6 \times 12 = 72 \]
-
Now, we can determine how many clementines Trisha brought: Let \( t \) be the number of bags Trisha brought. The total number of clementines she brought would be: \[ \text{Clementines from Trisha} = t \times 12 \]
-
Set up the equation for the total number of clementines: The total number of clementines brought by Sal, Trisha, and Joe is 180: \[ \text{Clementines from Sal} + \text{Clementines from Trisha} + \text{Clementines from Joe} = 180 \] Substituting the values we calculated: \[ 48 + (t \times 12) + 72 = 180 \]
-
Combine the known values: \[ 120 + 12t = 180 \]
This is the equation that can be used to determine how many bags Trisha brought. If you solve for \( t \), you will find the number of bags of clementines Trisha brought.
