# Martina uses n beads for each necklace she makes. She uses 2/3 that number of beads for each bracelet she makes. Which expression shows the number of beads Martina uses if she makes 6 necklaces and 12 bracelets?

She needs $14 n$ beads where n is the number of beads used for each necklace.
Let $n$ be the number of beads needed for each necklace. Then the beads needed for a bracelet is $\frac{2}{3} n$
$6 \times n + 12 \times \frac{2}{3} n = 6 n + 8 n = 14 n$
