If 
of an unknown number is 
, what is the unknown number?
If
First, we will need to convert 
to a decimal.
Now, the word "of" means we will need to multiply 0.05 by our unknown number, 
. Set that equation to 18, since that is what the problem tells us.
Now, divide both sides by 0.05

Jimmy is a salesman who is paid a base salary of 
per month. He also receives a 
commission on all his sales. If Jimmy sold 
worth of goods one month, how much was he paid for that month?
Jimmy is a salesman who is paid a base salary of
We can write the following equation to represet Jimmy's salary:
Because we know Jimmy sold $1920 this month, we can plug it into the above equation.
Now, convert the percent into a decimal to find how much Jimmy made this month.
