To find the price Avery would have to pay after applying a 20% discount, she can multiply the original price by \(0.80\). This is because a 20% discount means she pays 80% of the original price.
In mathematical terms:
1. The original price is represented as \(P\).
2. The discount is 20% of \(P\), which can be calculated as \(0.20 \times P\).
3. The amount she needs to pay after the discount is the original price minus the discount:
\[
P - (0.20 \times P) = P \times (1 - 0.20) = P \times 0.80.
\]
Thus, to find the price she would pay after the discount, she should multiply the prices on the tags by **0.80**.
