f(x + h) - f(x)
==========
x + h  - h
50/6 - 51/6 =( -1/6+ h)/h 
The h's will disappear when the limit is taken.
answer - 1/6 which is A. If anyone else answers take their answer. 
        
             
        
        
        
The answer is 0.5 metres.
4/2 = 1/2 
1/2 100cm is 50cm
50cm = 0.5 metres.
        
             
        
        
        
E+(e-24)=126
2e-24=126
2e=150
e=75
So (s)he recieved 75 and 75-24=51 emails  on those days.
