Business Rate Schedule

A utility company has the following rate schedule for natural gas usage in a city's business district. 

Monthly service charge $8.80 per therm service charge:

1^st 25 therms: $0.6686/therm

Over 25 therms:  $0.85870/therm

a)      What is the charge for using 25 therms in one month?

b)      What is the charge for using 45 therms in one month?

Construct a function that gives the monthly charge C for X therms of gas.

2.) Graph the following function using transformations.  Be sure to graph all of the stages on one graph all of the stages on one graph.  State domain and range.  For example, if you were asked to graph y=x² + 1 using transformation , you would show the graph of y = x² and the graph shifted up 1 unit.  Please do not show only the final graph. 

Y= -2|x| +2
