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?

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

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
