Lisa made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was $15.40 . If the beads cost $3.80 for each necklace, how much did each pendant cost?

Respuesta :

2 necklaces x $3.80 for each bead
$7.60
15.40 - 7.60
7.80
7.80 divide by 2
$3.90 for each pendant 
Divide by 2 you'll get 3.90
