Answer:

Explanation:

Comment

First we'll assume that a week includes Saturday and Sunday so the week has 7 days.

Equation

New bank balance = old bank balance - 7*22.50

New bank balance = old bank balance - 157.50 <========

Remark

The equation given above shows that her old balance decreased by 22.5 for 7 days. The bank would not run a statement like the one I gave you. They would take each one of the separate entries and subtract from the previous day's entry. Both entries would have a date and maybe a time associated with them.

Math people do it the way I have done it.
