Answer 1

the average homeowner would pay $321.10 annually to run appliances and refrigeration.

Explanation:

Given:

Average home uses 13,000 kWh of electricity per year.

Appliances and refrigeration account for 13% of total usage.

Electricity costs $0.19 per kWh in a particular area.

To find the cost of running appliances and refrigeration per year:

Step 1: Calculate the amount of electricity used by appliances and refrigeration.

The percentage of electricity used by appliances and refrigeration is 13%, so we can calculate the amount of electricity used by multiplying the total electricity usage by 0.13:

Appliances and refrigeration usage = 13,000 kWh x 0.13 = 1,690 kWh

Step 2: Calculate the cost of electricity for the amount used by appliances and refrigeration.

The cost of electricity per kWh is $0.19, so we can calculate the cost of running appliances and refrigeration by multiplying the electricity usage by the cost per kWh:

Cost of running appliances and refrigeration = 1,690 kWh x $0.19/kWh = $321.10

Therefore, the average homeowner would pay $321.10 annually to run appliances and refrigeration.
