Sally made $0.5\times 20=10$ shots originally. Letting $x$ be the number of shots she made, we have $\frac{10+x}{25}=0.60$. Solving for $x$ gives us $x=$ $(E)5$ 
After Sally takes 20 shots, she has made $50 \textbackslash\%$ of her shots. After she takes 5 more shots, she raises her percentage to $60 \textbackslash\%$. How many of the last 5 shots did she make? (adapted from 2004 AMC 8, Question\#6)
