Aheat pump with the COP of 2.1 supplies heat at the rate of 135 kJ/min. If a bar heater was used and the electricity cost R2.50 per kWh peak and 200 cents off-peak , how much would be saved using the heat pump for 7 days if the off-peak hours are from 22:00 hr to 6:00 hr for every day of the week.  Provide the answers to 2 decimal places and insert the unit in Rands after the answer
