A certain household being supplied from a 220-V source has the following devices/electrical loads in its electrical system with corresponding number of hours of usage: a) 7 LED bulbs rated 12 W each and energized 11 hours per day; b) A 120-Ω resistive device energized 3 hours a day; c) A certain appliance that draws a constant 2.75-ampere current 6 hours a day; d) A one-half horsepower motor that pumps water 2 hours daily; and e) Other loads that added 56 kWh to the total monthly consumption. If the electric utility company that supplies the electricity charges P9.45 per kWh, how much will be the household’s energy bill for a month. Consider a 30-day month period.

Question
A certain household being supplied from a 220-V source has the following
devices/electrical loads in its electrical system with corresponding number of hours of
usage:
a) 7 LED bulbs rated 12 W each and energized 11 hours per day;
b) A 120-Ω resistive device energized 3 hours a day;
c) A certain appliance that draws a constant 2.75-ampere current 6 hours a day;
d) A one-half horsepower motor that pumps water 2 hours daily; and
e) Other loads that added 56 kWh to the total monthly consumption.
If the electric utility company that supplies the electricity charges P9.45 per kWh, how
much will be the household’s energy bill for a month. Consider a 30-day month period.
