\r\n" );
document.write( "In this problem, we have given the exponential raise for 9 years,\r\n" );
document.write( "and the question asks about this exponential function 3 years later.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In order for to make calculations minimal, I will apply a trick: I will find first \r\n" );
document.write( "the coefficient of growth in 3 years, and then will use it to answer the question.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, let R be the coefficient of growth in 3 year. Then I can write this equation\r\n" );
document.write( "\r\n" );
document.write( "    13.35 = ,\r\n" );
document.write( "\r\n" );

document.write( "    R =  = 1.191108685.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Having it, the answer to the problem's question is in one line:\r\n" );
document.write( "\r\n" );
document.write( "    their hourly wage in 3 more year is  13.35*1.191108685 = 15.90  (rounded as requested).    ANSWER\r\n" );
