3 weeks
Step-by-step explanation:
To find the number of weeks, we have to equate the amount already saved and planned to save by both each week.
So we can write the expression as, 
 Let w be the number of weeks.
25 + 5w =16 + 8w 
Grouping the terms as, 
25 - 16 = 8w - 5w 
 9 = 3w 
Dividing both sides by 3, we will get, 
3w/3 = 9/3
  w = 3 
 So number of weeks = 3
