Amy made 3 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 3 necklaces was $13.20. If the beads cost a total of $6.90, how much did each pendant cost

the cost of each pendant is $2.1

Step-by-step explanation:

Let x represent the cost of each pendant.

Amy made 3 identical necklaces, each having beads and a pendant. It means that the cost of the pendant used is $3x. The total cost of the beads and pendants for all 3 necklaces was $13.20. If the beads cost a total of $6.90, then the equation would be written as

6.90 + 3x = 13.20

3x = 13.20 - 6.90

3x = 6.3

x = 6.3/3

x = 2.1

the answer is d. (1.2, -4.7) on edgn

hope this !
