Answer:
The solution of the given inequality  n < 5
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given inequality 
                      
<u><em>Step(i)</em></u>:-
  Cross multiplication '4' we get
                     8 n - 12 < 4 ( n +2)
                     8 n - 12 < 4 n + 4×2
                     8 n - 12 < 4 n +8
        Subtracting  '4 n ' on both sides, we get
                  8 n - 4 n - 12 < 4 n - 4 n +8
                  4 n - 12  <  8
<u><em>Step(ii):-</em></u>
Adding ' 12 ' on both sides , we get
                 4 n -12 + 12 < 8 + 12
                                4 n < 20
Dividing "4' on both sides , we get
                                  n < 5
The solution is n < 5
<u><em>Conclusion:-</em></u>
The solution of the given inequality  n < 5
 
        
             
        
        
        
The answer is 38, because if you take away the 15 he bought afterwards (34-15) you get 19, and then since he sold half his collection you would double that (19×2) and that's 38.
