Question

Your family uses a hot water heater to heat water for showers. It uses 0.2 kWh of energy per gallon of water used (kWh stands for kilowatt-hour, which is the way the electric company measures your energy use). The cost of a kWh is $0.10/kWh. Your family uses 30,000 gallons of hot water per year for showers. How much money will you spend on electric energy to heat the water for your family showers for a DAY? (365 days/year).

Answer 1

$1.64 per day to the nearest cents

Step-by-step explanation:

total amount of energy used

= 0.2 kWh/gallon × 30,000 gallon

= 6,000 kWh

total cost per year for usage

= 6,000 × $0.10/ kWh

= $600

cost per day = $600 ÷ 365 = $1.643835616 ≈ $ 1.64
