Question
Solve the following problem on separate paper being sure to show all supporting work. Answer any "interpret"
questions in full sentences including proper units. There are two parts to this problem.
The table below shows the electricity rates charged by Bright Light Utilities in the winter months.
Winter (November-June)
Base Charge: $7.00
First 500 kWh or less at 0.0550/kWh
Over 500 kWh at 0.0950/kWh
This table is translated into the following piecewise function where W(x) is the monthly fee and x is the number of kWh
used in that winter month.
0.0550x +7 Osx< 500
W(x) =
34.50 + 0.0950(x - 500)
500 <x
Use the given piecewise function associated with the table above to evaluate and interpret the meaning of each of the
following:
a. W(200)
b. W(800)
