Weegy: Well first, to find out how much he made, we need to figure out the percentage. To do this turn 20% into a decimal by dividing by 100. Then take that number and multiply it by the number of calls he made. 20/100= .2. [ 150 * .2 = 30
So he made commission on 30 of his calls. Since he made $6 per successful sale, multiply $6 by 30 and he made a whopping $180.
Hope this helped
