Question

Maria made 4 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 4 necklaces was$28.80. If the beads cost $3.40 for each necklace, how much did each pendant cost?

Answer 1

4=$28.80
$3.40+3.40+3.40+3.40=13.6
28.80-13.6=15.2
15.2/4=3.8
Each pendant cost $3.8 dollars

Answer 2

$28.80 / 4 = $7.20 (cost per necklace)

$7.20 - $3.40 = $3.80 (cost of each pendant)

Check:

4 * 3.40 = 13.60

4 * 3.80 = 15.20

13.60 + 15.20 = 28.80
