+p+-+.09p+=+81900+
+.91p+=+81900+

+p+=+90000+

x= selling price
x*(9%)=commission paid Convert your percent into a decimal by dividing it by 100 or simply moving the decimal to the left 2 places. 9%=0.09
The profit is the left over after the commission is paid.
x - .09x = 81,900
Simplify.. 1-.09
0.91x=81,900
Divide both sides by 0.91 to get x alone
x= 90,000
To check your work, take the proposed 90,000 selling price * 9%(0.09).
The commission would be $8,100
Selling price - commission = profit
Leaving you with a profit of $81,900.
:) *Don't forget your units when reporting your solution. $90,000
