My Friend wants a 30% Return How to calculate

[Michael McKenzie]

Hey BP my friend wants to help with a rehab flip that cost 15K he said he is willing to put in 10K but he wants a 30% return back on his 10K. 

The ARV for home is 120k

The price I got for home is 80K 

Repairs 15K

My buddy is putting 10K toward repairs 

I'm putting 5k towards repairs

Closing cost 7K

Agent Fee 4.4% 

What can I return my buddy ( He will only do deal if I can give him 30% of his money back)
