Hong made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was 10.40 If the beads cost 2.50 for each necklace, how much did each pendant cost?
b+ p= 10.40 b=2x 2.50 Now using substitution method replace b in first equation with value of second equation basically combing the two equations into one do you end up with one variable to solve . 2 x 2.50 +p =10.40 5 + p=10.40 P=$5.40 b =$5.00 The answer is EACH pendant cost $2.70 (You have to divide 5.40 by two )
