Thats what the website says, but note that fuel is at $2.24, need to adjust for your field, your insurance, etc. But a close average. Note: This doesnt not include the cost (loan) for the aircraft.
 
Local (pattern) type work, I would say yes. Average on a X-C might be 4. I would figure at 5 or 6 personally. I havent flown a 150 in many, many years. Other here, how about it?

Isn't it more like 6 gallons an hour?

I had exactly the same thought....

My 1978 152 POH has it at 5.7 GPH at 2400 RPM at 4,000 feet at ISA. Get it up to 12,000 at you can drop that number to 4.8.
 
I gotta argue with some of those figures:

A Cessna 150 is gonna burn closer to 6gph than 4. Good news is you can burn autogas is you buy the STC. It's a piece of paper that makes it legal, costs $100.

$20 an hour for maintanence? An annual where nothing is wrong would cost me about $500. I double that and budget $1000. Yeah, you could run into a major problem that cost more but setting aside $20 an hour for maintanence is overkill.

Engine reserve $8/hr? I've never worried about engine reserve. I wouldn't buy a plane I was planning on overhauling unless it was really cheap. I'd buy one with 500 hours on it and fly it to 1000 hours and sell it.

I own a 152 and haven't really worried about what I spend on it. One thing for sure, I don't fly it enough. I spend $15 an hour on gas (high grade autofuel). Set aside $10/hr for maintenance. Insurance is about 1K a year for full coverage. I paid 23.5K for it but dumped 10K into the panel, to include a Garmin 430 IFR approach approved moving map GPS/comm. I'd guess I might be able to get 30K out of the plane because it's an aerobat and the GPS. Check ebay, nice 150's can be had in the upper teens.
