Bill works as a car salesman. last week his total sales were $23,078.00, and he received $1,384.68 in commission. what is his rate of commission?

The best thing to do here is to divide the larger number by the smaller number, and this will give you the answer. 
23,078/1384.68 is 16.666
This means that his rate of commission is 16.666 or 1/6
Hope this helps :)

The operation is suck a c@ck? !
