He starts off with 300 in his savings. 4 weeks he gets 50 more.
So from what I see, 4 divided by 50. You will get 12.50 a week. 12.50 in first week. Second week goes up to $25. 3rd week then becomes 37.50. Fourth week of the month, add another 12.50 and it goes to $50 added to the savings.
Now after 8 weeks, it goes up another $50. So you basically just throw in another 4 to the first.
For instance, first 4 weeks he gets $50. The 4 weeks after, add another $50.
So I would say 12.50 a week.
