To solve the problem, we need to set up the equation based on the information given. Yuri sold 14 boxes, and together they sold a total of 37 boxes. Therefore, we can express the total number of boxes sold as:
Yuri's boxes + Trina's boxes = Total boxes sold
This can be written as:
14 + n = 37
Now, to isolate n (the number of boxes Trina sold), we can rearrange this equation:
n = 37 - 14 n = 23
Thus, the equation that represents the number of boxes Trina sold is:
n + 14 = 37; Trina sold 23 boxes.
So the correct response is: n + 14 = 37; Trina sold 23 boxes.
