Answer: 6,987,000 pounds fo CO₂ per kWh.
Step-by-step explanation: <u>Quilowatt</u>-<u>hour</u> <u>(kWh)</u> is a unit of energy that measures the amount of energy expended in 1 hour.
The AC uses 850 Watts, which in kW is 850,000 kW
If you leave the AC on for 6 hours, it will consume
850,000(6) = 5,100,000 kWh
Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:
1.37 .(5,100,000kWh) = 6,987,000 pounds
If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.
So ok
reduced by 13% each times 100-13=87 so 87 % of previous
so
t=time elapsed
I=initial amount
C=future amount
C=I(percentrate)^t
