The electricity rates charged by Monroe Utilities in the summer months are as follows: Base Charge = $7 First 600 kWh or less at $0.05/kWh Over 600 kWh at $0.08/kWh a. Complete the piecewise definition of the monthly charge $F(x)$ for a customer who uses $x$ kWh in a summer month. $F(x) = \begin{cases} S(x) ; & 0 < x \le a \\ L(x) ; & x > a \end{cases}$ Where: $S(x) = $ $L(x) = $ and $a = $ Which of the following is the graph of the piecewise function? 100+ 80 60 40 20 0 200 400 600 800 100 -20 -40 -60

The electricity rates charged by Monroe Utilities in the summer months are as follows: Base Charge = $7.50 First 800 kWh or less at $0.04/kWh Over 800 kWh at $0.07/kWh a. Complete the piecewise definition of the monthly charge F(z) for a customer who uses z kWh in a summer month: F(z) = $7.50, if 0 < z ≤ 800 $0.04z + $7.50, if z > 800 Where: F(z) represents the monthly charge for a customer who uses z kWh in a summer month. z represents the number of kWh used by the customer.

Electricity rates. Table 3 shows the electricity rates charged by Monroe Utilities in the summer months. The base is a fixed monthly charge, independent of the $\mathrm{kWh}$ (kilowatthours) used during the month. (A) Write a piecewise definition of the monthly charge $S(x)$ for a customer who uses $x$ kWh in a summer month. (B) Graph $S(x)$. Base charge, 8.50 dollar First $700 \mathrm{kWh}$ or less at $0.0650 / \mathrm{kWh}$ Over $700 \mathrm{kWh}$ at $0.0900 / \mathrm{kWh}$
