Niel has a bucket of beads. He uses them to make 8 identical necklaces and then buys 25 beads at the store. He ends up with a total of 500 beads. How many did he start with? Identify the operations needed to solve this problem using the equation b
§ + 25 = 500. (1 point)
O subtraction and division
O addition and multiplication
O addition and division
O subtraction and multiplication
The correct answer is O addition and subtraction.
To solve the problem, we need to use addition to add the number of beads Niel started with (represented by the variable b) to the number of beads he bought at the store (25). This gives us the total number of beads he had after purchasing the additional beads.
The equation representing this operation is b + 25 = 500.

The correct answer is O subtraction and multiplication.
To solve the problem, we need to use subtraction to find out how many beads Niel had left after making the necklaces. This is represented by b - 8, where b is the number of beads Niel started with.
Then, we need to use multiplication to calculate the total number of beads Niel had after buying 25 more. This is represented by (b - 8) * 25.
Finally, we can set up the equation (b - 8) * 25 = 500 and solve for b to find out how many beads Niel started with.
