percent question

% increase$=\frac{(\text{final value minus initial value})}{\text{absolute value of the initial value}}\cdot 100$ And in this example: $\frac{77-50=27}{\text{initial value}=50}=\frac{27}{50} \cdot100$   

I'll leave it up to you to simplify $\downarrow$ Hope this helps!

                                 Answer=$\frac{27}{50} \cdot 100$

great job LoryLullic :D

i dont know much latex, so i will try to explain without it.

If you subtract 50 percent from 77 percent, its 27 percent. We can say that 50 percent IS 100 percent. 77 would then inscrease by 27 percent, but since 50 percent is half of 100 percent, we need to multiply by two, so we get a 54 percent inscrease

(How did i do :D)

so we see that it increases by 27 and the original number is 50 so it is 27*100=2700 and then we divide by 50 to get 2700/50=54

so our final answer is 54
