Hello there! So, he sells a home worth $270,000 and gets 2.5% of that price as commission. In order to find the amount of commission he gets from selling that home, all you have to do is multiply the price by the percent, because commission is a small portion of the sold price. 270,000 * 2.5% (0.025) is 6,750. There. Jimmy's commission is $6,750.
