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?
Thoughts? Step-by-step reasoning:
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.
Thus, the answer is 100000.
