More like 35 to 50 dollars service charge.
You would have been hit with a service charge Tuesday, Wednesday and Thursday.
I don't care what you put in the bank Friday.
That's how real banks work. Close the account before they take it all.
Even if the average daily balance is real you never know when they start. They are just as likely to end the period on Monday and you can't put enough inbnthe bank to cover it. Banks live in their own time frame.
(1125+850+625+400+f)/5=1000
f=2000

You have 3000
so 2000+3000=5000 makes your daily balnace 1000
