Hi Ghf (lovely name btw, is it pronounced as it is spelled...jk),
For this problem you start with $50. Then during each of the next three months, there is a change in that $50 that is displayed in the table. For example, there is 12 less dollars by the end of the February, yielding a total account balance of $38 for the end of February (50-12=38). Now, continue with the changes given in the table but going from the previous' month's end account balance. So you would add $30 for March to the $38, and so on for April.
I hope this helps!
