With what ??? I don’t see nothing 
        
             
        
        
        
If 
1 bushel = 48 pounds
and 1 pound = 3 apples
       48 pounds = x apples               cross multiply
x apples = 48 X 3 ==> 144 apples
1 bushel = 144 apples (because 48 pounds = 1 bushel)
315 bushel = x apples
x apples = 144 X 315
x = 45360 apples
        
             
        
        
        
Multiply 120 by .2 to get 24
