Ronald wants to make profits by re-selling some phones he bought a week ago. He bought 200 units for just $3000, and he wants to gain a third of the initial investment in profits when all units are sold. Including the profit margin, what will be the selling price for each phone? Let's think step by step and output the final answer after "####".

The profit Ronald wants is $3000 / 3 = $<<3000/3=1000>>1000
The profit per phone sold will be $1000 / 200 phones = $<<1000/200=5>>5/phone
The cost of each phone is $3000 / 200 phones = $<<3000/200=15>>15/phone
The selling price including the profit will be $15/phone + $5/phone = $<<15+5=20>>20
