shannon opens a savings account with 50$ starting with the first week each week she deposits 8$ into her account how many weeks dose it take her to save 450$

I don't know if you are using one of those formulas but this is my answer

Step-by-step explanation:

She starts off with $50 so you can take that away from the $450. This means she has $400 to collect and save.

So 400/8 = 50

So I'm guessing it would be 50 weeks.

I could be wrong, if I am then I apologize!
