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

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.
