If a hotdog stand has a fixed expense of $225 a day, and a variable expenses of $0.45per hot dog, what would be the total expense to it of selling 273 hot dogs in a day?

expense of  selling 273 hot dogs in a day is 12285

Step-by-step explanation:

0.45 × 273

4 trillion pounds.

1 gigawatt-hour is equal to 1,000,000 kilowatt-hours.

Out of our 4,000,000 gigawatt-hours, 50% of it comes from coal; this is 2,000,000 gigawatt-hours.

2,000,000(1,000,000) = 2,000,000,000,000 (2 trillion) kilowatt-hours.

Since each kilowatt-hour is 2 lbs of carbon dioxide, 2 trillion * 2 = 4 trillion lbs of carbon dioxide.
