Ashley's salary is 20 percent less than kelly's. Ashley's salary is $300. How much more is kelly's salary than Ashley's?
Let's say Kelly's salary is x.
If Ashley's salary is 20 percent less than Kelly's, then Ashley's salary is 100% - 20% = 80% of Kelly's salary.
Since Ashley's salary is $300, then 80% of Kelly's salary is $300
80/100*x = $300
0.8x = $300
The value of x is $300/0.8 = $375
Kelly's salary is $375 - $300 = $<<375-300=75>>75 more than Ashley's salary. Answer: \boxed{75}.
