Let the cost of each pendant is x then the cost of
6 pendant is 6x.
Given each necklaces has a pendant
Hence, the cost of pendant for all 6 necklaces is 6x
Given, the cost of total beads is $14.40
Hence, the total cost of the beads and pendants of
all 6 necklaces is 6x + $14.40.
Given, the total cost of the beads and pendants of all
6 necklaces is $31.80
Hence 6x + $14.40 = $31.80
=> 6x = $17.40
=> x = $2.90
Hence, the cost of each pendant is $2.90
