If he spent half of his allowance, then he still has half of it left.  

 

So, the half he has left, plus the seven he earned, total eighteen.  

 

Take seven away from eighteen and you have eleven.  That's the half he has left.    

 

Since eleven is half his allowence, twice that is his entire allowance.  Allowance is 22 dollars
