Lamar made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $43.80If the beads cost $3.80 for each necklace, how much did each pendant cost?

3.50

Step-by-step explanation:

Necklace has beads and a pendant

b +p

There are 6 necklaces at a cost pf 43.80

6(b+p) =43.80

The beads for one necklace cost 3.80 so replace b with 3.80

6(3.80+p) =43.80

Divide each side by 6

6(3.80+p)/6 =43.80/6

3.80 +p = 7.30

Subtract 3.80 from each side

3.80+p-3.80 = 7.30 -3.80

p =3.50

the correct answer is the second option

its a straight line parallel to the time axis
