Answer 1

Utilities generally charge their consumers based on how much electricity they use. This means that as your usage increases, so will your bill.

Option D is the correct spending amount, Chloe spends $176.40 a month based on the cost of running the air conditioner per day.

The amount Chloe spends per day is:

$= 7 \text{ hours} \text{ x } 0.21 \text{ per hour}\\\\ = 1.47 \text{ dollars}$

In the 4 months, she will spend:

$= \text{Cost per day x 30 days x 4 months}\\\\ = 1.47 \text{x} 30 \text{x} 4\\\\ = 176.40 \text{dollars}$

Therefore, Chloe spends $176.40 per year on air conditioning.
