Final answer:
To find out how many plastic beads are on clearance, multiply 80 by 0.8.
Step-by-step explanation:
To find out how many plastic beads are on clearance, we need to find 80% of the total beads on clearance.
We know that 80% of the 80 beads on clearance are made of plastic.
To calculate this, multiply 80 by 80% (or 0.8).
80 * 0.8 = 64
Therefore, there are 64 plastic beads on clearance at Betty's Beading Boutique.
