First, we need to calculate the total amount of energy used by the clothes dryer in kilowatt-hours:
5 kW * 1.5 hours = 7.5 kWh
Next, we need to calculate the cost of using the clothes dryer:
7.5 kWh * $0.08/kWh = $0.60
Therefore, it cost $0.60 to dry this load of laundry.
5 kW * 1.5 hours = 7.5 kWh
