Question

Laura made 3 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 3 necklaces was $21.30. If the beads cost a total of $10.50, how much did each pendant cost?

Answer 1

3 identical necklaces, each with beads and a pendant

total cost for all 3 = $21.30

beads cost total $10.50

pendants total cost = 21.30-10.50 = 10.80

each pendant cost 10.80/3 = $3.60
