Question

Quizplus · Accepted Answer

Let the number of bracelets be $b$ and the number of necklaces be $n$. We have two equations from the problem statement: $b + n = 120$ (total pieces of jewelry) and $8b + 15n = 1100$ (total cost). Solving these equations simultaneously, we find that $b = 100$ and $n = 20$, which corresponds to option D.
