To find the equation that represents the number of boxes Trina sold, we can set up the equation based on the information given:
Yuri sold 14 boxes and together they sold a total of 37 boxes. Therefore, the number of boxes Trina sold (n) can be found with the following equation:
\( n + 14 = 37 \)
This equation states that the number of boxes Trina sold plus the number of boxes Yuri sold equals the total number of boxes sold.
Now, we can solve for \( n \):
- Subtract 14 from both sides: \[ n = 37 - 14 \]
- Calculate: \[ n = 23 \]
So, Trina sold 23 boxes.
The correct response is: n + 14 = 37; Trina sold 23 boxes.
