To find the equation that represents the number of boxes Trina sold, we can start with the information given:
- Yuri sold 14 boxes.
- Trina sold n boxes.
- Together, they sold a total of 37 boxes.
We can set up the equation based on the total:
\[ n + 14 = 37 \]
This equation correctly represents the situation. Now, to find the number of boxes Trina sold (n), we can solve for n as follows:
- Subtract 14 from both sides:
\[ n = 37 - 14 \]
- Calculate:
\[ n = 23 \]
So, Trina sold 23 boxes.
Thus, the correct answer and equation from the provided options is:
n + 14 = 37 ; Trina sold 23 boxes.
