A commercial building uses an air conditioning system with a capacity rating of "5-tons". It can remove sufficient heat to convert five tons, which also equal to 4545 kg, of water at 0.0°C into ice within twenty-four hours. The AC runs for 10 hours every weekday when the external temperature averages around 38°C while maintaining an internal temperature of 20°C. If the electricity cost is $0.12/kWh and efficiency is just 15% compared with an ideal refrigerator, find out what the daily and monthly costs are for cooling this particular building. The latent heat of fusion for water is 333,000 J/kg.
