A realtor'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.
