Question

Goran made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $33.60 . If the beads cost $2.90 for each necklace, how much did each pendant cost?

Answer 1

    6b + 6p = 33.60              ; b=2.90

6(2.90) + 6p = 33.60

17.40 + 6p = 33.60
-17.40           -17.40

    6p = 16.20
     /6         /6

      p = 2.70

ANSWER: each pendant costs $2.70
