It also cost him $25 to register each of these.  How much did he pay for everything?

conversations.value: The dirtbikes cost 3*150=$450
  The off-road vehicles cost 300*4=$1200
  He had to register 3+4=7 vehicles
  That means registration cost 25*7=$175
  So the total cost of everything was 450+1200+175=$1825
