At the 2018 Tompkins County Fair a vendor is offering a "fair special" on shoes. If you buy one pair of shoes at the regular price of $\textbackslash$ 80$, you get a second pair at a $34\textbackslash\%$ discount, and a third pair at half the regular price. James took advantage of the "fair special" to buy three pairs. What percentage of the $\textbackslash$ 240$ regular price did he save? (adapted from 2013 AMC 8, Question \#12)

First, the amount of money one will pay for three hats without the discount $=\textbackslash$ 240$. Then, find the amount of money using the discount: $80+0.66\times 80+\frac{1}{2} \times 80=\textbackslash$ 172.8$. Finding the percentage yields $\frac{172.8}{240}=72\textbackslash\%$ To find the percent saved, we have $100 \textbackslash\%-72\textbackslash\%= 28\textbackslash\%$
