Question: Mrs. Choi purchased a house for $80000. Five years later, she sold it for a 20% profit and got a 5% broker's commission from the original price. How much did the house sell for?
Answer: Step-by-step reasoning process: The 20% profit amounts to $80 000 x 20 / 100 = $16 000. The 5% commission amounts to $80 000 x 5 / 100 = $4 000. So the selling price is $80 000 + $16 000 + $4 000 = $100 000.
So the answer is 100000.

Question: 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?
Answer: Step-by-step reasoning process: 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.

Question: Brian is a real estate agent. He makes a 2% commission on each sale. During June, he sold three houses. The houses sold for $157,000, $499,000, and $125,000. What was Brian’s total commission on these three sales?
Answer:
Step-by-step reasoning process: Brian sold houses for 157,000 + 499,000 + 125,000 = $781,000 in total. Brian's commission was 781,000 * 0.02 = $15,620.
So the answer is 15620.
