In case you wanted one:

#!/usr/bin/env ruby

begin
  # You could also require csv but it seems like overkill for the sample.
  File.open(ARGV.first.to_s, 'r') do |fh|
    fh.readline # Drop headers.
    fh.each do |line|
      cols = line.split /,|\n/
      puts '%s is %.02f' % [cols[0], cols[1].to_f * cols[2].to_f]
    end
  end
rescue Errno::ENOENT
  puts 'Please pass the filename on the command line.'
  exit 1
end
