the formula for simple interest is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i = p * r * n\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f = p + i\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "combine the two formulas together and you get f = p + p * r * n.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factor out the p to get f = p * (1 + r * n).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i is the interest
\n" ); document.write( "p is the present value or principal
\n" ); document.write( "r is the interest rate per time period
\n" ); document.write( "n is the number of time periods.
\n" ); document.write( "f is the future value\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in your problem:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p equals 6000
\n" ); document.write( "r = .07 per year
\n" ); document.write( "n = 10 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formula becomes 6000 * (1 + .07 * 10) = 6000 * 1.7 = 10200.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you calculated it separately from i = p * r * n and then f = p * i, you would get the same result.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i = p * r * n becomes i = 6000 * .07 * 10 which becomes 4200.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f = p + i becomes f = 6000 + 4200 which becomes 10200.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
