Fabio is a video salesman. On each sale, he earns a commission of 12%. One of his customers bought a TV for $550 and a VCR for $400. How much did he earn in commissions?

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

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
