Need Help Finding Ticket Prices For The Ravens(Project)

[Valentin]

So my math teacher has asked us to do an excel project using a relation, so I thought it would be interesting to put the amount of tickets sold(alongside their prices each year) while comparing it to how good the Ravens did that year.

However, I'm not finding much in the way of actual ticket data. I can find the prices for this year, and one site told me the price from 2007, but not much else

If anyone could direct me towards a site with reliable data on the matter, that'd be great. I'm not sure if this is the right sub forum to post in, but any help is appreciated.
