Step-by-step explanation:

 
        
                    
             
        
        
        
First 700-25=675
Poppy= 2F (F as in Felix, since she sells twice as much)
Alex = (Now equals 2F as well, cus we already took away the 25)
And well.... Felix is just felix so add that all up
F+F+F+F+F=5F
675/5=135!
Now according to that 135 is how many felix sold
Felix=135
Poppy=270
Alex=295
