The region east of plain A is 50 square miles less than the region east of plain B. If plain B has 200 square miles, how many square miles do the plains have in total?
The region of plain A has a total of 200 - 50 = <<200-50=150>>150 square miles.
The total number of square miles for both plains is 150 square miles for plain A + 200 square miles for plain B = <<150+200=350>>350 square miles
#### 350
Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

It takes Jennifer 20 minutes to groom each of her 2 long hair dachshunds.  If she grooms her dogs every day, how many hours does she spend grooming her dogs in 30 days?She has 2 dogs and it takes 20 minutes to groom just 1 dog so it takes her 2*20 = <<2*20=40>>40 minutes per day to groom 2 dogs
In 30 days, she will have spent 30*40 = <<30*40=1200>>1,200 minutes grooming her dogs
There are 60 minutes in an hour so she spends 1200/60 = <<1200/60=20>>20 hours grooming her dogs

Tommy is making steaks for his family. There are 5 of them in total. If each member wants one pound and the steaks are 20 ounces each, how many does he need to buy?He needs 80 ounces of steak because 5 x 16 = <<5*16=80>>80
He need 4 steaks because 80 / 20 = <<80/20=4>>4

Now, solve this next question in the style of the above examples:

The region east of plain A is 50 square miles less than the region east of plain B. If plain B has 200 square miles, how many square miles do the plains have in total?

### Response:
The region of plain A has a total of 200 - 50 = <<200-50=150>>150 square miles.
The total number of square miles for both plains is 150 square miles for plain A + 200 square miles for plain B = <<150+200=350>>350 square miles
