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 what method is used for this problem?

Answer 1

The method used for this problem is the algebraic method.

To solve the problem using the equation "b8 + 25 = 500," we need to isolate the variable "b" (the number of beads Niel started with).

First, subtract 25 from both sides of the equation:
(b8 + 25) - 25 = 500 - 25
b8 = 475

Next, divide both sides of the equation by 8:
b = 475 / 8

Using division, we can find that b ≈ 59.375. However, since the number of beads cannot be fractionary, Niel started with approximately 59 beads.
