Best bet would to toss this into either an object or array for simplification, otherwise that type
of syntax would need the use of eval.
example: eval('echo $trivia_answer_'.$correct_answer.';');
best bet would be to..
$trivia_answer = array();
$trivia_answer[1] = 1000;
$trivia_answer[2] = 1250;
$trivia_answer[3] = 2500;
$trivia_answer[4] = 5000;
echo $trivia_answer[$correct_answer];
