I need some help with my hw, please :)

Practice Example: For a large boiler, you have the choice of the following energy sources. Calculate the POU cost per GJ for each. - Fuel Oil #2@\$0.8/liter, 39,000 kJ/liter, Efficiency 89\% - Electricity@\$0.095/kWh, Efficiency 98\% Practice Example: For a large boiler, you have the choice of the following energy sources.
