Scott made 3 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 3 necklaces was $14.40.If the beads cost a total of $5.70, how much did each pendant cost?

$2.90

Step-by-step explanation:

Lets look at the information given:

Scott made 3 necklaces

$14.40 is the cost for both the beads and pendants for all 3 necklaces

$5.70 was the cost of just beads for all 3 necklaces

Each necklace has 1 pendant

The first step to solving this equation is subtracting the cost of the beads from the total cost for the necklaces:

$14.40 - $5.70= $8.70

Now we know that cost for the 3 pendants for all 3 necklaces was $8.70, but we need to find how much EACH pendant costs. To find out, we simply divide the total cost for all 3 pendants by 3:

$8.70 ÷ 3 = $2.90

So each pendent costs $2.90
