If total is 4%, then, calculate the amount for traditional way for a house sold in 400,000, you'll find it will be 4% for total (100000*0.07 + 300000*0.03)/400000 = 0.04, so the same for both.

Let's try to calculate the rate for the traditional way: y = (0.07*100000 + (x-100000))/x => y=4000/x + 0.036 x0 }* t( n# S% n& {% z

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.., o+ v$ T* R( F

Note: above comparison is based on the assumption: 2% realtor means 2% for each side realtor (i.e., total 4%) + \# s$ J y' I1 X
