Arealtor's commission is directly proportional to the selling price of a house. mr. wiley earned a commission of $9,200 on a house that sold for $184,000. at this rate, what would mr. wiley's commission be on a house that sells for $250,000?

Mr. Wiley earned a commission of $9,200 on a house that sold for $184,000.
At this rate, Mr. Wiley's commission be on a house that sells for $250,000 = ?
commission = price of house sold
$9,200 = $184,000 
multiply both sides with $250,000
$9,200 x $250,000 = $184,000 x $250,000
when the price is $250,000, the commission will be;
($9,200 x $250,000) / $184,000 = $250,000
$2300000/$184 = $250,000
$12,500 = $250,000
Thus, the commission is $12,500.
