Question

Ken sold $700 worth of digital cameras, $2,394 worth of laptops, and $833 worth of vacuum cleaners. Digital cameras cost $175 each, laptops cost $399 each, and vacuum cleaners cost $119 each. If Ken earns a $35 commission for each sale, how much did he earn in commissions in all?

Answer 1

digital cameras : 700/175 = 4 sales
laptops : 2394/399 = 6 sales
vacuum's : 833/119 = 7 sales

for a total of : (4 + 6 + 7 = 17)...17 sales....and he receives $ 35 per sale...so he earned (17 * 35) = $ 595 in commission <==
