Suppose the Jackson family use the following appliances on a typical day in October: Plasma TV (uses 250 watts per hour), used for 6 hours Microwave oven (uses 900 watts per hour), used for 30 minutes Refrigerator (uses 600 watts per hour), used for 24 hours Freezer (uses 400 watts per hour), used for 24 hours Determine how many kilowatts is used by these 4 appliances in a 31-day month. Round your final answer to the nearest tenth.

Question
Suppose the Jackson family use the following appliances on a typical day in October:
Plasma TV (uses 250 watts per hour), used for 6 hours Microwave oven (uses 900 watts per hour), used for 30 minutes Refrigerator (uses 600 watts per hour), used for 24 hours Freezer (uses 400 watts per hour), used for 24 hours
Determine how many kilowatts is used by these 4 appliances in a 31-day month. Round your final answer to the nearest tenth.
Expert Solution
Introduction
We know power is rate of energy transfer or mathematically,
P=E/t and E= P t
Energy consumption of family of appliances for 1 day
- TV, (250W/hr) x 6 hr. = 1500 watt
- Microwave oven, (900 W/hr) x (30/60) hr = 450 watt
- Refrigerator, (600 W/hr) x 24 hr = 14400 watt
- Freezer, (400 W/hr) x 24 hr = 9600 watt
