They together have $15 with which they can buy 15 bars. These 15 bars will generate 15 wrappers.
Now we will utilise the given fact i.e. 3 wrappers can buy 1 bar. Hence with the 15 wrappers, we can buy 5 bars.
With these 5 bars, # of wrappers generated are 5, of which 3 are utilised to get another bar and 2 are left.
The last bar will further give a wrapper that when combined with the leftover 2 wrappers will yield us another bar.
All in all 22 bars.
