Danny wants to sell his house. He would like to receive $136,000 after deducting the 6% commission due to the real estate agent.
Alex17521 [72]

Answer:

The selling price of the house is $144,681

Step-by-step explanation:

The computation of the selling price of the house is shown below:

Let us assume the selling price be x

So, the commission would be 0.06x

Now the danny would received

= x - 0.06x

= 0.94x

And, the amount received is $136,000

So equate this value

Like this

0.94x = $136,000

x = \frac{\$134,000}{0.94}

= $144,681

Hence, the selling price of the house is $144,681
