Commission Melanie receives a 3% commission on every house she sells. If she received a commission of $8571, what was the value

katrin2010 [14]

Given:

The percentage rate of commission, R=3%.

The commission recieved by Melanie, C=$8571.

The expression for commission amount is,

$C=\frac{R}{100}\times SP$

Here, SP is the sale price of the house.

Put R=3% and C=$8571 in the above equation to find sale price.

$\begin{gathered} 8571=\frac{3}{100}\times SP \\ SP=\frac{8571\times100}{3} \\ SP=285700 \end{gathered}$

Therefore, the sale price is $285700.
