Give me the answer explain cause i can’t learn like that not trying to be rude

There are approximately 4 weeks per month.

Mr. Gleason will take home 1100 x 4 weeks = $4,400 per month.

The total budget - his take home pay is the amount his wife will need to make:

5,600 - 4,400 = $1,200

Now divide the total amount she needs to make by how much she brings home per hour:

1,200 / 10 = 120

 She needs to work 120 hours per month.

The answer is D.
