The burritos have 10*120=<<10*120=1200>>1200 calories

That means he gets 1200/6=<<1200/6=200>>200 calories per dollar

The burgers get 5*400=<<5*400=2000>>2000 calories

So he gets 2000/8=<<2000/8=250>>250 calories per dollar

So he gets 250-200=<<250-200=50>>50 more calories per dollar from the burgers
