Talia gave her hairdresser a 20 percent tip, which amounted to $7. What was the price of the service before the tip?

A:
I don't know if I did it right but here's my guess. I think you multiply 7 by 20% and that gives you 1.40 as a result. Compared to the other method I used (division), I'm pretty sure I'm right since the other result was 35. Doesn't make sense if the end amount was $7.
