<span>We find the total commission earned by calculating the amount of commission he earned in each sale and then finding their sum.
Price of TV = $550
Commission =12%
Amount of Commission earned = (12/100)*550
= $66
Price of VCR = $400
Commission = 12%
Amount of Commission earned =(12/100)*400
=$48
Total Commission earned = $66 + $ 48
=$114</span>
Given that Fabio earns 12% commission for every sales he makes, the total amount he earned for selling a TV that cost $550 and VCR for $400 will be: commission=[percentage commission]/100*[total amount sold] total amount sold=550+400=$950 commission=12/100*950 =$114 therefore he earned $114 as commission
