Step-by-step explanation:
Well, this is a function. In order to solve this, you need a v value. Once you get a v value, you can plug into into 6+v^2 and wala- you get your answer. 
Example, lets say 
v is 3 
then 
F(3) = 6 + 3^2
f(3) = 6 + 9
f(3) =15

Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
 You would then want to subtract that from the amount she started with in her account.
 The equation becomes: Y = 150 - 15x
