18. The waste-to-energy process generates
energy in the form of electricity, heat, or fuel
from the incineration of waste. Converting
non-recyclable waste materials into electricity,
heat, or fuel generates a renewable energy
source. The 86 waste-to-energy facilities
in the United States have the capacity to
produce 2,720 megawatts of power per
year by processing more than 28 million
tons of waste per year. Write an inequality
to show the possible power, p, that the
waste-to-energy facilities in the United States
are capable of producing.
