###Human: A house’s living room, dining room and kitchen take up 1,000 sq ft. The house also has a guest bedroom and a master bedroom suite. If the guest bedroom is a quarter of the size of the master bedroom suite, and the house is 2,300 sq ft total, how large is the master bedroom suite?, ### Assistant: The house is 2,300 sq ft and we know the non-bedroom sections take up 1,000 sq ft, so that leaves 2300-1000 = 1,300 sq ft for the bedrooms/bathrooms
Let x be the size of the master bedroom suite.
Then the guest bedroom is 0.25x.
So together the bedrooms are x + 0.25x = 1.25x in size.
This means 1.25x = 1300
So x = 1300 / 1.25 = 1040 sq ft 
 So the answer is :  1040
