So based on the model the 5 small units of the remaining money is equal to 1 unit of total money.
Hence 1 small unit = 1/5 unit
So his total remaining money = 9 small units.
Now, if 1 unit = 5 small unit
4 unit = 20 small units
Since 4+5=9 small units is his remaining money, 20-9=11 small units is the $165 he initially spent.
Hope this helps !
