You can put this solution on YOUR website!
the formula of f = p * (1 + r) ^ n can be used to solve this.\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( "the formula becomes:
\n" ); document.write( "16500 = 14000 * (1 + r) ^ 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r is the interest rate per quarter.
\n" ); document.write( "n is the number of quarters = 3 * 4 = 12.
\n" ); document.write( "p is equal to 14000.
\n" ); document.write( "f is equal to 16500.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "divide both sides of the formula by 14000 to get:
\n" ); document.write( "16500 / 14000 = (1 + r) ^ 12
\n" ); document.write( "take the third root of both sides of the equation to get:
\n" ); document.write( "(16500 / 14000) ^ (1/12) = 1 + r
\n" ); document.write( "solve for 1 + r to get:
\n" ); document.write( "1 + r = (16500 / 14000) ^ (1/12) = 1.013786085.
\n" ); document.write( "subtract 1 from that to get:
\n" ); document.write( "interest rate of .013786085 per quarter.
\n" ); document.write( "multiply that by 4 to get:
\n" ); document.write( "nominal interest rate per year = .05514434 per year.
\n" ); document.write( "that's the same as 5.514434 per cent nominal interest rate per year.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you could also solve this by calculator as shown below:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "inputs are;\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "output is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the result from the calculator is the percent interest rate per quarter.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "multiply that by 4 to get nominal interest rate percent of 5.514432 per year.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the very slight difference between the manually calculated results and the financial calculator results is due to rounding of the intermediate results in the display of the calculator.\r
