Westside Energy charges its electric customers a base rate of $8.00 per month, plus 10¢ per kilowatt-hour (kWh) for the first 300 kWh used and 2¢ per kWh for all usage over 300 kWh. Suppose a customer uses x kWh of electricity in one month. (a) Express the monthly cost E as a piecewise defined function of x. (Assume E is measured in dollars.) E(x) = O (b) Graph the function E for 0 ≤ x ≤ 600.
