comparing 2 realtors using above formular, you will see : 1) if total sale value (x in the formular) > 400,000, traditional realtor < 0.04, then traditional is better since it's < 0.04; 2) total sale value < 400,000, 2% realtor is better since traditional one > 0.04 3) if sale value is 400,000, both are the same..
