idk but I hope you the best of luck
Not absolutely sure I understand the question, but should be 120
Answer:
y=-15x+50
Step-by-step explanation:
You originally had 50 dollars, so +50. Then, it decreases at a rate of 15 every week, so -15x.
Y is the total number of money she has.
y= -15x+50
formula is 
where A=final amount
P=principal
r=interest rate in decimal
n=number of times per year it is compounded
t=time in years
we want to find where
A=2P
and P=5745
and r=6.5%=0.065
n=monthly=12
remember that 
also that 
, solving for t
divide both sides by 5745 to simplify things a bit
I'd rather not simplify this because it give us a decimals and those aren't exact, if we combine, we get 12.065/12 for inside parenthases

take ln of both sides


divide both sides by 

using our calculator, t≈10.6927
so rounded, we get 10.7 years
