Q1
You live in Houston and expect to use 1200 kWh this month. Compare two electricity plans (delivery charges are the same for both). Plan H1: base charge $9.95 + 12.0¢/kWh for the first 1000 kWh, then 9.0¢/kWh above 1000 kWh; TDU delivery: $4.39 per month + 3.89¢/kWh. Plan H2: no base charge, flat 13.2¢/kWh for all usage; same TDU delivery charges. Which plan gives the lower total bill for 1200 kWh?
