Please take care to read Joost's answer carefully, spotting the needed differences. Perl has two quoting approaches: single quotes (that basically don't interpolate) and double quotes (that do interpolate). So:
my $variable = 42;
print 'this is $variable'; # prints   this is $variable
print "this is $variable"; # prints   this is 42
