<span>the existence of an individual human being or animal.</span>
Răspuns:
100%
Explicație pas cu pas:
Permiteți numărul inițial de fotografii = x
x - 50% din x = x - 0,5x = 0,5x
0,5x + câte% din 0,5x = x
x - 0,5x = y% de 0,5x
0,5x / 0,5x = 1
Prin urmare,
100% = 1
Prin urmare, x trebuie mărit cu 100% pentru a reveni la numărul original.

For this case we have an equation with a variable of the form 
. Where 
. Given the value of
, we want to find the value of the variable "x". So, we have:
We must clear "x", for this, we add "19" to both sides of the equation:
We divide between "3" on both sides of the equation:
Thus, the value of the variable "x" is 30.
Answer:
Option A
