\n" ); document.write( "\n" ); document.write( "\"SI+=+PTR\"
\n" ); document.write( "SI, or simple interest = 28,800 - 21,200, or $7,600
\n" ); document.write( "P = $21,200
\n" ); document.write( "T = 6 (in years)
\n" ); document.write( "R = annual interest rate\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We then get: \"7600+=+21200%286%29%28R%29\" ----- \"7600+=+127200R\" ------ \"R+=+7600%2F127200\"\r
