Their savings will be same after 25 weeks.
Step-by-step explanation:
The difference in both person's saving is $ 2/week
$5-$3=$2
The total difference in the starting point is $50 if we divide $50 by $2 we will get a number of 25 which is the number of weeks it will take both savings to reach at a same level
