Question description

Monthly service charge: \$8.80
Per therm service charge 1st 25 therms: \$0.6686/therm
Over 25 therms: \$0.85870/therm

therefore for the first 25 therms in a month,
8.80 + 0.6686(25) = ?

and for 45 therms in a month,
8.80 + 0.6686(25) + 0.85870(45-25) = ?

For x therms in a month,
Between zero and 25:
f(x) = 8.80 + 0.6686x for 0 ≤ x ≤ 25

Greater than 25:
f(x) = 8.80 + 0.6686(25) + 0.85870(x-25) for x > 25
Just simplify this function.
