Nell makes 11.78 per hour. if she works 40 hours a week and about 4 weeks per month, what is the maximum monthly rent that she can afford to pay?

Since there are no choices given, let us just solve how much "Nell" will earn per month.

Given: 11.78 per hour
            40 hours a week
            4 weeks per month

Let us multiply 11.78/hr with 40 hrs/week. 
11.78 × 40 = 471.2
==> Nell will earn 471.2 per week
Multiply the result with 4 to see how much Nell will earn every month.
471.2 × 4 = 1884.8

==> Nell will earn 1884.4 per month, this means she can afford to rent and still has money left on her pocket for other basic needs.
