Steve recieves a commission of $500 per sale on the first 4 sales he makes a $600 per sale for the next 6 sales he makes during a month. what is the average commission steve recieves per sale during a month?

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.
