museum

I think i got this one...but then again..i think i didnt

A Native American art museum charges $8 per visit to nonmembers. Members pay a $40 membership fee and get in for a reduced rate of $5. How many times must a pereson visit the museum for membership to be less expensive than paying for each visit as a nonmember?

i did:

8x > 40 + 5x
-5x.........-5x
---
3x > 40
---....---
3.......3

x > 13.3

Nicely done, but you haven't actually answered the question.
