Question

Joe made

4
identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all
4
necklaces was
$
25.60
. If the beads cost
$
2.70
for each necklace, how much did each pendant cost?

Answer 1

Each pendant costs $3.70.

Explanation:

Let's assume that the cost of each pendant is x dollars.

The total cost of the beads for all 4 necklaces is 4 * $2.70 = $10.80.

The total cost of the beads and pendants for all 4 necklaces is $25.60.

So, the total cost of the pendants for all 4 necklaces is

$25.60 - $10.80 = $14.80.

Since there are 4 necklaces and each necklace has a pendant, the total cost of all the pendants is 4x dollars.

So we can write

4x = $14.80

Dividing both sides by 4, we get

x = $3.70

Therefore, each pendant costs $3.70.
