phil smith is a car salesman. Last week his total sales amounted to $27,650.00, and he received $1,382.50 in comission. What is his rate of commission?
The problem has to do with finding what percentage is one quantity over another. We can solve as a rule of three, knowing that $27,650 is the 100% $27,650 ----> 100% 1382.5 ------> x
x = (1382.5)(100)/27650 x = 5 therefore, $1382.5 is the 5% of $27650
