(Hint: about a quarter) b) How many pounds of carbon dioxide will be emitted in that hour?Explanation / Answer
a)
Total Natural Gas Consumed by wall heater
N=60 /2 =30 cubic feet
So Cost of natural gas
C=(30/100)*1 = $0.3
b)
1 therm =100 cubic feet
100 cubic feet =>11.7 pounds of carbondioxide is released into atmosphere ,
The amount of carbondioxide released into atmosphere in 1 hour is
W =(30*11.7)/100 =3.51 pounds
