Is a $700. con ed bill possible if...?

Question

all you run is a central air conditioner. my finances grandma says she gets a $700. con ed bill every month and she just has central air and i'm assuming gas. i run a home recording studio which is on all the time. i stupidly leave my lights on all day i also run two air conditioners constantly and my con ed bill is normally $140.

Answer 1

Only if she has it set on freezer mode, and leaves all of the doors and windows open, while constantly baking, cooking and running the hot water.

Answer 2

i highly doubt that that she has a 700 a month bill, unless she has a bunch of heat lamps for her pot growing operation
