Question

The average home uses about 11,000 kilowatt-hours (kWh) of electricity per year. Appliances and refrigeration account for about 13% of this total. If electricity costs $0.15 per kWh in a particular area, how much would theaverage nomeowner pay annually to run appliances and refrigeration?

Answer 1

`\text{ \$}214.50`

Step-by-step explanation:

Here, we want to get the amount incurred by running appliances and refrigeration

Firstly, we need to calculate the KWh used by these activities

This is 13% of the total

Thus, we have that as:

`(13)/(100)*\text{ 11,000 = 1,430 kWh}`

To get the cost of this, we have to multiply by $0.15

Mathematically, we have that as:

`0.15\text{ }*\text{ 1430 = \$214.50}`
