Select the correct answer.
anastasia had a part-time job last year. she made $20 per hour and worked every week of the year. each week she worked 7 hours. she paid her monthly expenses and saved the rest of her earnings. at the end of the year, she had $2,000 in savings. what were her average monthly expenses, rounded to the nearest dollar?
a.
$440
b.
$473
c.
$475
d.
$568

A. $440

Step-by-step explanation:

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.

5280/12= 440.

I hope this answer helps you.

i'm not sure i quite understand, could you provide more information?

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
