A daily power consumption profile of a customer is shown in the table below, where the kilowatt loads are averaged over the period listed and kilovolt-ampere demand meter readings are peak values over 15-min intervals during the period. This pattern repeats for all days in a 30-day month. The utility tariff to this consumer is 12 cents/kWh plus $15 per peak kilovolt-ampere demand over the month. Determine the monthly utility bill: 

(1) With the present usage pattern and 

(2) With the pf improved to unity. Also, determine the daily load factor of this consumer as seen by the utility company.
