Thats likely a cpm ad on your site that pays around 32 cents cpm. So sayeth the windows calculator. Anyways, $7/50 is $0.14 cents a click, which is not bad at all. I actually get paid around $7 per 25 clicks, but I've only had 25 clicks in February..
Now I really wish I had that many clicks a day, then 60$ would be enough to afford an all day laziness and push the TV switch once in a while
