Solve for Missing Value: 37 - 30 Bracelets Word Problem

To solve this problem, follow these steps:

• Step 1: Calculate the original number of bracelets that Maya and Rachel have together. Maya has 20 bracelets, and Rachel has 17, so initially, they have $20 + 17 = 37$ bracelets.
• Step 2: Determine how many bracelets they have after giving some to Danielle. Together, they now have 30 bracelets.
• Step 3: Calculate the number of bracelets given to Danielle by finding the difference between the original total and the current total. This is given by $37 - 30$.

Now, let's compute:

Initially, Maya and Rachel collectively had $37$ bracelets. After giving some to Danielle, they have $30$ bracelets. Therefore, the number of bracelets they gave to Danielle is $37 - 30 = 7$.

The correct answer is $\mathbf{7}$ bracelets.

Thus, the correct choice from the provided options is Choice 4: $7$.
