You can put this solution on YOUR website!
the equation to use for this is f = p * (1 + r) ^ n
\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( "your time periods are in years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when p = 12000 and r = 5% per year / 100 = .05 per year and n = 2028 - 2019 = 9 years, then the equation becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f = 12000 * (1 + .05) ^ 9 = 18615.93859\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "round to the nearest penny = 18615.94\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the interest earned is 6615.93859.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "round to the nearest penny = 6615.94.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that becomes the present value and n becomes 5 and r stays at .05 per year.
\n" ); document.write( "the formula becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f = 6615.93859 * (1 + .05) ^ 5 = 8443.800443.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "round to the nearest penny to get 8443.80.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the interest after 5 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the additional interest earned is 8443.800443 minus 6615.93859 = 1827.861852.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "round to the nearest penny to get additional interest earned = 1827.86.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your questions was how much will the interest earn after 5 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i believe the answer to that would be 1827.86.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a summary of what happened.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "12000 grew to 18615.94 in 9 years.
\n" ); document.write( "interest earned was 18615.94 - 12000 = 6615.94
\n" ); document.write( "6615.94 grew to 8443.80 in 5 years.
\n" ); document.write( "interest earned was 8443.80 - 6615.94 = 1827.86\r
