Use the simple interest formula I = Prt.\r
\n" ); document.write( "\n" ); document.write( "Then substituting, we get 158.07 = (4790)(r)(2) = 9580r\r
\n" ); document.write( "\n" ); document.write( "==>\"r+=+158.07%2F9580+=+0.0165\"\r
\n" ); document.write( "\n" ); document.write( "Therefore, the monthly rate of simple interest is 1.65%.
