Question

Greg made 2

 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was $8.40

. If the beads cost $2.40

 for each necklace, how much did each pendant cost?

Answer 1

2(P+B) = 8.4

P+B = 4.2

2B = 2.4 (if you meant both beads cost $2.40)

B = 1.2

P = P+B-B = 4.2-1.2= $3 per each pendant
