A gas company has the following rate schedule for natural gas usage in single-family residences:
Monthly service charge $8.80
Per therm service charge
1st 25 therms $0.6686/therm
Over 25 therms $0.85870/therm
What is the charge for using 25 therms in one month? Show your work.
What is the charge for using 45 therms in one month? Show your work.
Construct a function that gives the monthly charge C for x therms of gas.
Explanation / Answer
C(x)=8.80+ 0.6686 x , 0<=x<=25
C(x)= 8.80+0.85870, 25<x<=45
C(25)=8.80+0.6686(25)=25.515
C(45)=8.80+0.85870(45)=47.4415
