Answer 1

To solve the equation \( b \cdot 8 + 25 = 500 \), we need to identify the operations involved.

1. The term \( b \cdot 8 \) represents the multiplication of the number of beads \( b \) used for each necklace by 8 (the number of necklaces).
2. The equation then adds 25 (the beads Niel buys) to that total.
3. Finally, the equation sets the result equal to 500 (the total number of beads he has).

Thus, the operations needed to solve this problem are:

• Multiplication (to find the total number of beads used for the necklaces)
• Addition (to add the purchased beads to the total from the necklaces)

The correct response is: addition and multiplication.
