Answer:
I believe the answer would be A, she needs to save less each month.
Step-by-step explanation:
If she is extending the amount of time she has to save, then she wouldn't need to save as much per month. If she saved at the same rate or more she would be going over her desired amount, and knowing that she only wants to save the same amount, she would have to save less each month in order to not go over the ammount she plans on saving. Hope this helped :)
