so get the people down to unit rates first
Natalie= 40 in 9 minutes
Steven= 10 in 3 minutes
multiply Stevens to get it even

30 in 9 minutes
so Natalie paints faster
hope I was helpful
X could either be 4 or 5, depending on which x the question asks. If you have to chose one answer go with 5 because it's associated with the y.
