Yuri and Trina sold boxes of cookies. Yuri sold 14 boxes. Together, they sold a total of 37 boxes. Which equation represents the number of boxes Trina sold? How many boxes did she sell

n+37=14; Trina sold 23 boxes
n+14=37; Trina sold 23 boxes
n-14=37; Trina sold 51 boxes
n-37=14; Trina sold 51 boxes

What the right answer

1 answer

Let's set up the equation to find out how many boxes Trina sold.

Let \( n \) represent the number of boxes Trina sold. According to the problem:

  1. Yuri sold 14 boxes.
  2. Together, they sold a total of 37 boxes.

The equation that represents the situation is:

\[ 14 + n = 37 \]

To find \( n \) (the number of boxes Trina sold), subtract 14 from both sides:

\[ n = 37 - 14 \] \[ n = 23 \]

Thus, Trina sold 23 boxes.

The correct equation from the options listed is:

\( n + 14 = 37 \); Trina sold 23 boxes.
