Question

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  b8 + 25 = 500.

GPT 3.5 · Answer

To solve this problem, we can use the equation: b8 + 25 = 500, where b represents the number of beads Neil started with.

The operations needed to solve this problem using the equation are addition and subtraction. Adding the number of beads Neil started with (b) to the 25 beads he bought gives the total number of beads after buying the additional beads. Finally, subtracting this total from 500 gives the number of beads Neil started with.
