What is important to know here is how many weeks does the year have. A regular year has 52 weeks.
To calculate this we must first multiply the hours worked, the value of these and finally the weeks the year have.
7*20*52= 7280.
To the result of that, you must deduct the savings Anastasia had wich are $2000.
7280-2000= 5280.
$5280 is the amount of money spent on expenses for the entire year. If you divide that between the number of months a year has (12) you will reach the answer to the question.
