Firstly, draw models for B and H. The question has stated that 4/5 of B is equal to 1/2 of H.
So, after drawing 5 units of B, you can draw 1 unit of H (4 of B) this is for the first half of H. The other half should also be the same, so it is also made up of another 4 units of B.
The difference in H and B is the extra 3 units from H and you know this is the "$120 more". To find out 1 unit, simply 120/3=$40.
Total units of H is 8, thus 8*$40=$320.
