The 3 cars take 3*40=<<3*40=120>>120 minutes to make

He repairs 5-3=<<5-3=2>>2 more cars

They each take 40*.5=<<40*.5=20>>20 minutes longer per car

So they each take 40+20=<<40+20=60>>60 minutes

So he repaired cars for 120+2*60=<<120+2*60=240>>240 minutes

That is 240/60=<<240/60=4>>4 hours

So he made 4*20=$<<4*20=80>>80
