Question

Consider a refrigerator that consumes 320 W of elec- tric power when it is running. If the refrigerator runs only one quarter of the time and the unit cost of electricity is

Answer 1

Answer: The refrigerator cost in this month is $4.5 approximately.

Explanation:

Since we have given that

Amount of watt of electric power = 320 W

Number of days = 30

Unit cost of electricity = $0.13/Kwh

Hold factor =
`(1)/(4)`

Number of hours in a month = 24

So, the refrigerator cost in this month would be

`0.13* 0.32* (1)/(4)* 30* 24\\\\=\$7.488`

Hence, the refrigerator cost in this month is $4.5 approximately.
