When electricity became widely distributed during the early part of the 20th century, state governments regulated the electricity industry as a monopoly. One electric company had the rights to generate and distribute electricity for a city or a certain part of the state. In return, the government laid out a set of rules for what the electric company could and could not do. During the 1990s and early 21st century, many states deregulated electricity. As a result, numerous electric companies can now provide electricity for a particular area. One such company is Lights and Power. To attract customers, Lights and Power is advertising a special: Cheapest Electricity in Town! To 1.000 kWh-$0.11 per kWh More than 1,000 to 1,500 kWh-$0.18 per kWh More than 1.500 kWh $0.25 per kWh No hidden fees! We promise!

For what domain does your function model the cost of 1,001 to 1,500 kilowatt-hours of electricity? 8. Write an equation to describe the cost (m) of the number of kilowatt-hours of electricity (x) more than 1,500 kilowatt-hours. 9. For what domain does your function model the most of more than 1,500 kilowatt-hours of electricity? 10. Write three piecewise functions, including limitations on the domain, that describe the cost of purchasing electricity from Lights and Power
