document.write( "\r\n" );
document.write( "So, let X be the original deposited amount.\r\n" );

document.write( "\r\n" );
document.write( "From this equation, you find  X =  = P99,851.21.\r\n" );

document.write( "It is the starting value and, at the same time, is the present value.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The interest earned is the difference  P135,000 - P99,851.21 = P35,148.79.\r\n" );
