How do you write the following situation in function notation: Sadie has a bank account with a balance of $650.00 and plans to spend $55 per week?

Let #A(t)# be the amount of Sadie's bank account after #t# weeks.

We can write

#A(t)=650-55t#

I hope that this was helpful.

The function notation for Sadie's situation would be:

( f(w) = 650 - 55w )

Where:

( f(w) ) represents the balance of Sadie's bank account after ( w ) weeks.
( 650 ) is the initial balance of Sadie's bank account.
( 55 ) is the amount Sadie plans to spend per week.
