Question

Tammy made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $38.40. If the beads cost $2.60 for each necklace, how much did each pendant cost?

Answer 1

To determine the cost of each pendant, subtract the total cost of the beads ($15.60) from the total cost of all necklaces ($38.40) to find the cost of all pendants ($22.80) and then divide by the number of necklaces. Each pendant costs $3.80.

Step-by-step explanation:

To find the cost of each pendant, we must first determine the total cost of the beads for all 6 necklaces. Since the beads cost $2.60 for each necklace, the total cost for the beads in all necklaces is $2.60 x 6 = $15.60.

The total cost for all the necklaces, including beads and pendants, is $38.40. To find the total cost of the pendants, we subtract the total cost of the beads from the overall total, which gives us $38.40 - $15.60 = $22.80. This is the total cost for all 6 pendants.

Finally, to find the cost of each pendant, we divide the total cost of the pendants by the number of necklaces, which is 6. So, each pendant costs $22.80 ÷ 6 = $3.80.
