You first need to do an economy test, fill the tank and zero the trip meter, do as close to 100Km's and re fill note the distance covered, re fill car for fuel used this will give you an economy reading average only. Do this and let me know the readings.

Do a scan for fault codes, not all faults will set a check light.

Why do I scan for fault codes its not a check engine light, its my tank is empty light. When I just put 50 dollars into the tank drive 20 miles while driving on that 50 dollars worth of gas the gauge must be broke

Just to confirm your problem, you are concerned that the fuel gauge is dropping quickly correct? But is this also with poor fuel economy or just the gauge being inaccurate? If just the gauge replace the sender unit, if it is poor economy do as I suggested in earlier post.
