To solve the equation \( b \times 8 + 25 = 500 \), we can follow these steps:

  1. Identify the unknown variable \( b \), which represents the number of beads used for each necklace.
  2. Since Niel made 8 identical necklaces, the total number of beads used for the necklaces is \( b \times 8 \).
  3. After buying 25 more beads, he has a total of 500 beads.

To solve for \( b \):

  1. First, subtract 25 from both sides to isolate the term with \( b \): \[ b \times 8 = 500 - 25 \] \[ b \times 8 = 475 \]

  2. Next, divide both sides by 8 to find \( b \): \[ b = \frac{475}{8} \]

So, for the operations needed to solve the equation \( b \times 8 + 25 = 500 \), you would use subtraction and division.

The correct response is:
