Question

Jessica had m beads. She used 18 of them to make a necklace for her mom. Then she used the rest to make k bracelets for her friends, with the same number of beads in each bracelet. How many beads did she use to make each bracelet?

Answer 1

The expression to represent this would be (m-18)/k.

We first subtract the 18 beads she used in her mother's bracelet from her beginning number, m. We then divide our result by k, the number of bracelets she made for her friends.
