f = p * (1 + r) ^ n\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f is the future value
\n" ); document.write( "p is the present value
\n" ); document.write( "r is the interest rate per time period.
\n" ); document.write( "n is the number of time periods.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "350 crimes in 1990, so p = 350.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "rate = 2% / 100 = .02 per year.
\n" ); document.write( "n = 2021 - 1990 = 31 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f = 350 * (1.02)^31 = 646.6560855 in the year 2021.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's approximately 647.\r
