Carlos made two identical necklaces each having beads and a pendant. The total cost of the beads and pendants for both necklaces was $12.40. If the beads cost $2.80 for each necklace, how much each does dependent cost?

Step-by-step explanation:

So we know that:

Total Cost: $12.40

Beads per Necklace: 2.80

So the first thing we have to do is multiply 2.80 by 2 which equals 5.6 so that's how much of the total cost was for beads.

So now we subtract the amount of money for the beads and the total cost of the necklaces 12.40 - 5.6 = 6.8

So 6.8 was the amount of money that is left for the pendants. Now that we know that we have to divide that by 2 to find out how much money did Carlos spend for each pendant,

6.8÷2= 3.4

So Carlos spent 3 dollars and 4 cents on each pendant.
