Question

I AM ON MY LAST CHANCE TOO GET THIS CORRECT. Westside Energy charges its electric customers a base rate of $3.00 per month, plus 13¢ per kilowatt-hour (kWh) for the first 300 kWh used and 6¢ 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. E(x) = 3.00 + 0.13X if 0 ? x ? 300 41.00 + 0.06(x - 300) if 300 < x IS THIS CORRECT? IF NOT PLEASE HELP! HOW DOES 3.00 + 0.13X IF 0 ? X ? 300 EQUAL 41.00? (b) Graph the function E for 0 ? x ? 600.
