**Answer: a**

**Step-by-step explanation:**

So cost=(# of items) times (Price per item)

necklace=48 bbeads and 1 charm

1 bead=0.05

charm=0.45

so we multiply

necklace=48(0.05)+1(0.45)

necklace=2.4+0.45

necklace=2.85

bracelet=25 beads and 4 charms

bracelet=25(0.05)+4(0.45)

bracelet=1.25+1.8

bracelet=3.05

necklace=$2.85

bracelet=$3.05

Does that say 4 x 8x + 1 = 2(squared)x?
