Answer:
C.
Step-by-step explanation:
If each pack had 5 pieces, that would mean that every pack (p) would equal 5•p, or 5p. The question is asking how many total pieces she has. So if 5 pieces equals one pack, you would have to add the pieces she previously had to add those to 5p. We don't know how many packs she bought, so we would have to replace that number with a variable (p). So 5p + 3
