<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
For the 1 first problem you have to do additive inverse where the subtraction sign is and then combine all the z's and then combine the normal numbers and then put plus sign in between
