Ashley salary is 20 percent less than kelly. Ashley salary is $3000. How much more is kelly salary than Ashley?

Let's assume Kelly's salary is x.

From the information given, we know that Ashley's salary is 20% less than Kelly's salary.
So, Ashley's salary is x - 20/100 * x = x - 0.2x = 0.8x.
Given that Ashley's salary is $3000, we can set up the equation 0.8x = $3000.
Dividing both sides of the equation by 0.8 gives us x = $3000 / 0.8 = $3750.
Kelly's salary is therefore $3750 - $3000 = $<<3750-3000=750>>750 more than Ashley's salary. Answer: \boxed{750}.
