Amount of commission received by Steve for the first 4 sales of the month = $500 Amount of commission received by Steve for the next 6 sales of the month = $600 Amount of commission made by Steve for the first 10 sales of the month = (500 + 600) dollars = 1100 dollars Average commission received by Steve per sale during the month = 1100/10 dollars = 110 dollars So the average commission received by Steve for a single sale during the month is $110. I hope the procedure is clear enough for you to understand.
