Question

A family has a huge array of solar panels to make electricity. If each month they sell back 420 kWh for $0.07 per kWh, how much money could they make in a year

Answer 1

$352.80

Explanation:

We have been given a family sell back 420 kWh for $0.07 per kWh each month.

First of all, we will find monthly income of family from solar panels by multiplying 420 by $0.07.

`\text{Monthly income of family from solar panels}=420\text{ kWh}* \frac{\$0.07}{\text{kWh}}`

`\text{Monthly income of family from solar panels}=420*\$0.07`

`\text{Monthly income of family from solar panels}=\$29.40`

To find the money earned by the family is one year, we will multiply monthly income by 12 as 1 year equals to 12 months.

`\text{Annual income of family from solar panels}=\$29.40* 12`

`\text{Annual income of family from solar panels}=\$352.80`

Therefore, the family could make $352.80 in a year from solar panels.
