You can put this solution on YOUR website!
the formula to use for this problem is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "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( "in your problem:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f = 25000
\n" ); document.write( "p = what you want to find.
\n" ); document.write( "r = .05/12 (formula uses the rate, not the percent).
\n" ); document.write( "n = 5 * 12 = 60\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your time periods are in months, so rate per year is divided by 12 to get rate per month, and 5 years is multiplied by 12 to get 60 months.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "formula becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "25000 = p * (1 + .05/12) ^ (5 * 12)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for p to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p = 25000 / ((1 + .05/12) ^ (5 * 12)) = 19480.13476.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can also use a financial calculator like the one found at https://arachnoid.com/finance/index.html\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your inputs are shown below:\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the calculator uses the percent, not the rate.
\n" ); document.write( "you can't enter 5/12.
\n" ); document.write( "it doesn't know what to do with that.
\n" ); document.write( "you have to enter the result of 5/12 = .41666666667.
\n" ); document.write( "give it enough sixes so that it will give you a more detailed answer.
\n" ); document.write( "8 or 9 of them is enough.
\n" ); document.write( "you can round at the end with a 7, or just leave it as sixes.
\n" ); document.write( "the calculator will display only 6 of them and it will round the last digit displayed.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can see that the answer is the same as the one you got with the formula, except it's rounded to 2 decimal digits.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "either way, your answer is that the present value is 19,480.13 rounded to 2 decimal digits.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "it is important to get the interest rate per time period and the number of tiem periods right.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in this problem the time periods were in months.\r
