The correct answer is: (b/8) + 25 = 500 requires the operations of subtraction and division.
To solve this problem using the given equation b/8 + 25 = 500, we need to identify the operations needed.
The equation is stating that "the number of beads, divided by 8, plus 25 is equal to 500." So, we need to perform the following operations to find the value of b:
1. Division: We need to divide b by 8 to find the number of beads needed for each necklace. This operation is represented by the term b/8.
2. Addition: We need to add 25 to the number of beads required for 8 necklaces to account for the additional beads Niel bought at the store. This operation is represented by the term + 25.
The correct answer is: subtraction and division
