Admob Revenue

I have done some research on admob revenue with numbers all over the map.

Anyone have recent numbers they are willing to share? Impressions, CTR, average $ per month?

Does it make sense to even offer an app that consists of ads or is it really better just to charge for a purchase or subscription?

For the Last 28 days, Impressions = 145k , Estimated Earnings = $158
