Energy help. How much electricity do you use for a 1B1B?

My apartment is a 1B1B of 700 square feet. I am at home a lot, turn lights off at daytime and on at night, and keep my AC at about 75 degrees all day long.

My September electric bill is $121 of 1000+ kWh used… I felt it's kinda too much but don't know what I can do to save the bill… How much did you guys pay for a 1B1B like mine?
