Given:
Commision earned = $11,700
The commission was calculated at 6/100 of the selling price.
To find the selling price of the house, we have the equation:

Where S represents the selling price of the house.
Let's solve for S.
Multiply both sides of the equation by 100:

Divide both sides of the equation by 6:

Therefore, the selling price of the house is $195,000
