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
Part A) What is the charge for using 25 therms in one month? Show your work.
The charge for using 25 therms in one month = Monthly service charge + 1st 25 therms charge
= 8.80 + 25(0.6686) = $25.515
Part B) What is the charge for using 45 therms in one month? Show your work.
The charge for using 45 therms in one month = Monthly service charge + 1st 25 therms charge + 2nd 20 therms charge.
= 8.80 + 25(0.6686) + 20 (0.85870) = $ 42.689
