I am writing a script titled, "grades.pl." Essentially, it takes user input and returns a letter (A,B,C,D,F). My problem is that I don't know how to loop the variable, $grade, through the hash keys so that the input will return the corresponding value. 
$grade = <STDIN>;

%scores=( "$grades<=90" => "A", 
"$grade<=80" => "B", 
"$grade<=70" => "C", 
"$grade<=80" => "D", 
"$grade>=50" => "F");

foreach $grade (%scores) {
if ( $grade != key ) {
