Use the simple interest formula
\(\small{\textbf{1)}}\) \(p= $300 \,\,\) \(r=4\% \,\,\) \(t=3\) years \(\,\,\) \(I=\,?\) 
\(\small{\textbf{2)}}\) \(p=2000 \,\,\) \(r=3.5\% \,\,\) \(t=9\) months \(\,\, I=\,?\)
\(\small{\textbf{3)}}\) \(I=30 \,\,\) \(r=4\% \,\,\) \(t=2\) years \(\,\, P=\,?\)
\(\small{\textbf{4)}}\) \(p=4000 \,\,\) \(r=5\% \,\,\) \(I=$400\) \(\,\, t=\,?\)
\(\small{\textbf{5)}}\) \(p=1000 \,\,\) \(I=300 \,\,\) \(t=3\) years \(\,\, r=\,?\)
\(\small{\textbf{6)}}\) How long would it take \($350\) to grow to \($455\) with \(2\%\) simple interest?
\(\small{\textbf{7)}}\) If your money doubles in \(20\) years, what is the annual simple interest rate?
