Question

Uri and Trina sell boxes of cookies Uri sells 14 boxes. While Trina sold n boxes together, they sold a total of 37 boxes which equation represents the number of boxes Trina sold. How many boxes did she Sell
A. n+37=14 Trina sold 23 boxes
B. n-37=14 Trina sold 51 boxes
C. n+14=37 Trina sold 23 boxes
D. n-14=37 Trina sold 51 boxes

Answer 1

To find the equation that represents the number of boxes Trina sold, we start with the information given:

Uri sold 14 boxes, and together with Trina, they sold a total of 37 boxes.

This means that the number of boxes Trina sold can be represented by the equation:

\[ \text{Boxes sold by Uri} + \text{Boxes sold by Trina} = \text{Total boxes sold} \]

So we can write:

\[ 14 + n = 37 \]

Where \( n \) is the number of boxes Trina sold.

To solve for \( n \), you would subtract 14 from both sides:

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

So, Trina sold 23 boxes.

Looking at the options provided:

- A. \( n + 37 = 14 \) (Incorrect)
- B. \( n - 37 = 14 \) (Incorrect)
- C. \( n + 14 = 37 \) (Correct: this is the equation we derived)
- D. \( n - 14 = 37 \) (Incorrect)

Therefore, the correct answer is **C. n + 14 = 37. Trina sold 23 boxes.**
